The course focuses on simple and multiple linear regression as well as analysis of variance (ANOVA), analysis of covariance (ANCOVA) and binomial regression. The course is a natural continuation of a typical introductory course in statistics taught in various departments of the university.

We will discuss methods for estimating parameters in linear models, how to construct confidence intervals and test hypotheses for the parameters, which assumptions need to hold for applying the models and what to do when they are not met.

Students will work on projects using the statistical software R.

This course is a continuation of Biostatistics I and constitutes a practical guide to statistical analyses of student's own research projects. The course covers the following topics. Estimation of relative risk/odds ratios and adjusted estimation of relative risk/odds ratios, correlation and simple linear regression, multiple linear regression and logistic regression. The course is based on lectures and practical sessions using R for statistical analyses.

Students will perform traditional statistical analysis on real data sets. Special focus will be on regression methods, including multiple regression analysis. Students will apply sophisticated methods of graphical representation and automatic reporting. Students will hand in a projects where they apply the above mentioned methods on real datasets in order to answer research questions

The course covers methods for analysis of cohort studies using methods for time to event or survival analysis. It is based on the course Biostat III – Survival analysis for epidemiologists in R at the Karolinska Institutet: See (https://biostat3.net/index.html): "Topics covered include methods for estimating patient survival (life table and Kaplan-Meier methods), comparing survival between patient subgroups (log-rank test), and modelling survival (primarily Poisson regression, Cox proportional hazards model and flexible parametric models). The course addresses the concept of 'time' as a potential confounder or effect modifier and approaches to defining 'time' (e.g., time since entry, attained age, calendar time). The course will emphasise the basic concepts of statistical modelling in epidemiology, such as controlling for confounding and assessing effect modification." 

Participants in the course will obtain training in practical statistics as used when providing general statistical counselling. The participants will be introduced to actual statistical projects by assisting students in various departments within the university. The participants will report on the projects in class, discuss options for solving the projects and subsequently assist the students with analyses using R and interpretation of results.

The course constitutes a practical guide to the preparation of a health-related research study. Modules include: reference search and handling, development of hypotheses, creation of a systematic critical review within chosen field of research, development and presentation of research proposals.

The course is for graduate students who have chosen a field/research question for their dissertation project.

The aim of the course is for students to gain training in methods and insight into the implementation of a specific research project in public health. Students get to know the theoretical background of the research they are working on and are trained to participate in a defined part of it, but the topics depend on the needs of the research project that is assigned. An example would be e.g. participation in the preparation of a research project and various work related to data collection and data processing (cleaning and/or analysis). Students will also get to know the different aspects of the research project under the guidance of the scientific staff leading the research and in collaboration with the research team.

Students attend regular meetings with the researchers and supervisors of the course. The research training is planned specifically for each student with regard to the content and progress of the research, the supervisor and the student's background. Study space is limited by the research projects that are ongoing at the Center for Public Health Sciences at any given time, and students apply for registration for the course at the program office.

The MS program in Epidemiology and Biostatistics is a 120 credit post-graduate and cross-disciplinary program, including a 30 or 60 credit research thesis. Projects that have been/could be submitted for publication can be awarded 60 credits. During the first semester students develop their research questions and choose a thesis advisor. A complete research proposal is presented at the end of the second semester. Departmental registration is determined by the students' area of interest and host faculty of their main advisor.

The objective of the MS thesis is to provide training in constructing, organising, developing and conducting a research or developmental project in the public health sciences and an understanding of the technical limits, regulations, ethics and laws that must be observed in such work. Students should be able to define and present research questions and propose original hypotheses.

Special software is needed for such an analysis and the necessary packages are provided in R, STATA, and SAS. The application will be based on R but other programs will be introduced for comparison.
The course will be taught between beginning of September and end of November, meeting once a week. The teaching will be in a flipped class manner. All the material (both notes and lectures) are online (see below) and it is expected that students will have viewed the material before class. In class the theory will be discussed and then students are expected to work on the application on their own computer.

The course covers models used to work with the underlying variables in psychological measurements will be introduced. In the first course (Models for underlying variables I) we will work with confirmatory factor models and structural equation models (also known as path models). We will cover the assumptions of the models, how to work with them, and interpretation of results. Methods to work with different types of data will be discussed. In the second course (Models for underlying variables II) we will start by introducing methods for categorical variables and then move to the closely related item response models. Primary focus will be on models for binary data but the most common models for categorical data will be introduced. In the second part of the course, we will move on to models for longitudinal data that use underlying variables: latent growth models, cross-lagged product models, and models for intensive longitudinal methods (also known as Daily-diary data, Ambulatory assessment, or Ecological-momentary data). Emphasis will be on practical training in analyzing data with models through projects, as well as the theoretical basis of models.

The focus of this course is on Bayesian latent Gaussian models (BLGMs) which are a class of Bayesian hierarchical models and applications of these models. The main topics are three types of BLGMs: (i) Bayesian Gaussian—Gaussian models, (ii) BLGMs with a univariate link function, and (iii) BLGMs with a multivariate link function, as well as prior densities for BLGMs and posterior computation for BLGMs. In the first part of the course, the basics of these models is covered and homework assignments will be given on these topics. In the second part of the course, the focus is on a project, in which data are analyzed using BLGMs. Each student can contribute data that she or he wishes to analyze. The material in the course is based on a theoretical background. However, the focus on data analysis is strong, and computation and programming play a large role in the course. Thus, the course will be useful to students in their future projects involving data analysis.

The course on 12 weeks and will be on "flipped" form. This means that no lectures will be given but students will read some material and watch videos before attending classes. Students will then work on assignments during the classes.

The aim of this course is to enable student to conduct their own data analyses. This includes familiarizing them with practical aspects of data cleaning/processing and statistical methods used within nutritional epidemiology. 

Short lectures will be given covering selected subjects followed by practical assignments. Assignments will contribute 100% to the final grade. 

Some experience with SPSS, SAS or related softwere in addition to having taken basic course in statistics is desierable, but not required.

This is a comprehensive course in multiple-regression analysis. The goal of the course is that students develop enough conceptual understanding and practical knowledge to use this method on their own. The lectures cover various regression analysis techniques commonly used in quantitative social research, including control variables, the use of nominal variables, linear and nonlinear models, techniques that test for mediation and statistical interaction effects, and so on. We discuss the assumptions of regression analysis and learn techniques to detect and deal with violations of assumptions. In addition, logistic regression will be introduced, which is a method for a dichotomous dependent variable. We also review many of the basic concepts involved in statistical inference and significance testing. Students get plenty of hands-on experience with data analysis.

The focus of this course is on Bayesian latent Gaussian models (BLGMs) which are a class of Bayesian hierarchical models and applications of these models. The main topics are three types of BLGMs: (i) Bayesian Gaussian—Gaussian models, (ii) BLGMs with a univariate link function, and (iii) BLGMs with a multivariate link function, as well as prior densities for BLGMs and posterior computation for BLGMs. In the first part of the course, the basics of these models is covered and homework assignments will be given on these topics. In the second part of the course, the focus is on a project, in which data are analyzed using BLGMs. Each student can contribute data that she or he wishes to analyze. The material in the course is based on a theoretical background. However, the focus on data analysis is strong, and computation and programming play a large role in the course. Thus, the course will be useful to students in their future projects involving data analysis.

Linear regression models, the multiple normal distribution, hierarchical models, fixed and random effect models, restricted maximum likelihood estimation, best linear unbiased estimators, Bayesian inference, statistical decision theory, Markov chains,  Monte Carlo integration, importance sampling, Markov chain Monte Carlo, Gibbs sampling, the Metropolis-Hastings algorithm.

Emphasis will be placed on introducing the scientific foundation of the trauma field and understanding scientific articles in this area. The main topics of the course include:

• Prevalence of traumatic events and acute stress reactions.
• Mental health problems following trauma, such as posttraumatic stress disorder, anxiety, depression, sleep disturbances, substance abuse and prolonged grief.
• The disease burden of trauma, due to e.g., cardiovascular diseases, cancers, autoimmune diseases, and suicide.
• The influence of environmental and genetic factors in the development of psychological and physical diseases following trauma.
• Factors that promote recovery post-trauma and reduce the risk of long-term health problems.
• Evidence-based treatment options for PTSD.

The course is intended for students who want to increase their scientific knowledge of the relationship between trauma and health. It is only intended for postgraduate students. The course consists of lectures by the main supervisor and selected guest speakers who are experts in the field of trauma. Emphasis will be placed on discussions and active participation of students.

The course focuses on statistical analysis using the R environment. It is assumed that students have basic knowledge of statistics and the statistical software R. Students will learn to apply a broad range of statistical methods in R (such as classification methods, resampling methods, linear model selection and tree-based methods). The course on 12 weeks and will be on "flipped" form. This means that no lectures will be given but students will read some material and watch videos before attending classes. Students will then work on assignments during the classes.

The aim of this course is to enable student to conduct their own data analyses. This includes familiarizing them with practical aspects of data cleaning/processing and statistical methods used within nutritional epidemiology. 

Short lectures will be given covering selected subjects followed by practical assignments. Assignments will contribute 100% to the final grade. 

Some experience with SPSS, SAS or related softwere in addition to having taken basic course in statistics is desierable, but not required.

This is a comprehensive course in multiple-regression analysis. The goal of the course is that students develop enough conceptual understanding and practical knowledge to use this method on their own. The lectures cover various regression analysis techniques commonly used in quantitative social research, including control variables, the use of nominal variables, linear and nonlinear models, techniques that test for mediation and statistical interaction effects, and so on. We discuss the assumptions of regression analysis and learn techniques to detect and deal with violations of assumptions. In addition, logistic regression will be introduced, which is a method for a dichotomous dependent variable. We also review many of the basic concepts involved in statistical inference and significance testing. Students get plenty of hands-on experience with data analysis.

This course will cover the algorithmic aspects of bioinformatic. We  will start with an introduction to genomics and algorithms for students new to the field. The course is divided into modules, each module covers a single problem in bioinformatics that will be motivated based on current research. The module will then cover algorithms that solve the problem and variations on the problem. The problems covered are motif finding, edit distance in strings, sequence alignment, clustering, sequencing and assembly and finally computational methods for high throughput sequencing (HTS).

The course focuses on simple and multiple linear regression as well as analysis of variance (ANOVA), analysis of covariance (ANCOVA) and binomial regression. The course is a natural continuation of a typical introductory course in statistics taught in various departments of the university.

We will discuss methods for estimating parameters in linear models, how to construct confidence intervals and test hypotheses for the parameters, which assumptions need to hold for applying the models and what to do when they are not met.

Students will work on projects using the statistical software R.

This course is a continuation of Biostatistics I and constitutes a practical guide to statistical analyses of student's own research projects. The course covers the following topics. Estimation of relative risk/odds ratios and adjusted estimation of relative risk/odds ratios, correlation and simple linear regression, multiple linear regression and logistic regression. The course is based on lectures and practical sessions using R for statistical analyses.

This is a preparatory course for students in these interdisciplinary and research based studies. The course covers various practical issues, methods, study planning, refernce search, and scientific literacy e.g.. Students also aquire basic training in the statistical program R.

The course is an introduction to epidemiological research methods and causal inference. An overview is provided on measure of disease occurrence, measures of outcome (relative risks), and study design (experiments, intervention studies, cohort studies and case-control studies). Emphasis is on systematic errors and on methods to avoid such errors in planning (study design) and in data analyses. Students get training in reviewing epidemiological studies.

Students will perform traditional statistical analysis on real data sets. Special focus will be on regression methods, including multiple regression analysis. Students will apply sophisticated methods of graphical representation and automatic reporting. Students will hand in a projects where they apply the above mentioned methods on real datasets in order to answer research questions

The course covers methods for analysis of cohort studies using methods for time to event or survival analysis. It is based on the course Biostat III – Survival analysis for epidemiologists in R at the Karolinska Institutet: See (https://biostat3.net/index.html): "Topics covered include methods for estimating patient survival (life table and Kaplan-Meier methods), comparing survival between patient subgroups (log-rank test), and modelling survival (primarily Poisson regression, Cox proportional hazards model and flexible parametric models). The course addresses the concept of 'time' as a potential confounder or effect modifier and approaches to defining 'time' (e.g., time since entry, attained age, calendar time). The course will emphasise the basic concepts of statistical modelling in epidemiology, such as controlling for confounding and assessing effect modification." 

Participants in the course will obtain training in practical statistics as used when providing general statistical counselling. The participants will be introduced to actual statistical projects by assisting students in various departments within the university. The participants will report on the projects in class, discuss options for solving the projects and subsequently assist the students with analyses using R and interpretation of results.

The course constitutes a practical guide to the preparation of a health-related research study. Modules include: reference search and handling, development of hypotheses, creation of a systematic critical review within chosen field of research, development and presentation of research proposals.

The course is for graduate students who have chosen a field/research question for their dissertation project.

The aim of the course is for students to gain training in methods and insight into the implementation of a specific research project in public health. Students get to know the theoretical background of the research they are working on and are trained to participate in a defined part of it, but the topics depend on the needs of the research project that is assigned. An example would be e.g. participation in the preparation of a research project and various work related to data collection and data processing (cleaning and/or analysis). Students will also get to know the different aspects of the research project under the guidance of the scientific staff leading the research and in collaboration with the research team.

Students attend regular meetings with the researchers and supervisors of the course. The research training is planned specifically for each student with regard to the content and progress of the research, the supervisor and the student's background. Study space is limited by the research projects that are ongoing at the Center for Public Health Sciences at any given time, and students apply for registration for the course at the program office.

The MS program in Epidemiology and Biostatistics is a 120 credit post-graduate and cross-disciplinary program, including a 30 or 60 credit research thesis. Projects that have been/could be submitted for publication can be awarded 60 credits. During the first semester students develop their research questions and choose a thesis advisor. A complete research proposal is presented at the end of the second semester. Departmental registration is determined by the students' area of interest and host faculty of their main advisor.

The objective of the MS thesis is to provide training in constructing, organising, developing and conducting a research or developmental project in the public health sciences and an understanding of the technical limits, regulations, ethics and laws that must be observed in such work. Students should be able to define and present research questions and propose original hypotheses.

Goal: To train students in applying methods of Bayesian statistics for analysis of data. Topics: Theory of Bayesian inference, prior distributions, data distributions and posterior distributions. Bayesian inference  for parameters of univariate and multivariate distributions: binomial; normal; Poisson; exponential; multivariate normal; multinomial. Model checking and model comparison: Bayesian p-values; deviance information criterion (DIC). Bayesian computation: Markov chain Monte Carlo (MCMC) methods; the Gibbs sampler; the Metropolis-Hastings algorithm; convergence diagnostistics. Linear models: normal linear models; hierarchical linear models; generalized linear models. Emphasis on data analysis using software, e.g. Matlab and R.

The course is about the theory and application of random effects, or linear mixed models, and related models for correlated response variables. The course will cover methods for continuous and approximately normally distributed variables. A statistical model for such data has to describe both the expected value and the covariance between observations. The theory extends the theory of general linear models. Special software is needed for such an analysis and the necessary packages are provided in R, STATA, and SAS. The application will be based on R but other programs will be introduced for comparison.
The course will be taught between beginning of September and end of November, meeting once a week. The teaching will be in a flipped class manner. All the material (both notes and lectures) are online (see below) and it is expected that students will have viewed the material before class. In class the theory will be discussed and then students are expected to work on the application on their own computer.

The course covers models used to work with the underlying variables in psychological measurements will be introduced. In the first course (Models for underlying variables I) we will work with confirmatory factor models and structural equation models (also known as path models). We will cover the assumptions of the models, how to work with them, and interpretation of results. Methods to work with different types of data will be discussed. In the second course (Models for underlying variables II) we will start by introducing methods for categorical variables and then move to the closely related item response models. Primary focus will be on models for binary data but the most common models for categorical data will be introduced. In the second part of the course, we will move on to models for longitudinal data that use underlying variables: latent growth models, cross-lagged product models, and models for intensive longitudinal methods (also known as Daily-diary data, Ambulatory assessment, or Ecological-momentary data). Emphasis will be on practical training in analyzing data with models through projects, as well as the theoretical basis of models.

Univariate calculus (basic algebra, functi ons, polynomials, logarithms and exponenti al functi ons, conti nuity and limits, diff erenti ati on, local extrema andintegrati on).
Linear algebra (vectors, matrices, linear projecti ons with matrices, matrix inverses and determinants).
Programming in R (arithmeti c, functi ons and organizing R code).
Multi variate calculus (Jacobian, Hessian and double integrals).
The approach will be to address each mathemati cs topic using a mix of (a) basic theory (in the form of concepts rather than proofs), (b) computerprogramming using R to visualize the theory, and (c) examples exclusively from stati stics. Formal lectures are not planned, but students will be able toseek assistance with their weekly assignments.
The goal of the course is to cover the calculus, linear algebra and computer programming concepts most commonly needed in stati sti cs. A student who has completed this course should have the mathematical basis for statistics courses currently taught at the MSc level by the mathematics department(and thus also for all stati sti cs courses taught by other departments).

Students will author examples and multiple-choice questi ons, and their submissions will be graded by their peers.
