Overview

While the statistical models and tools presented in an introductory statistics course (such as linear regression) can be used to answer a wide range of questions in life sciences, many types of data cannot be analyzed using these simple approaches.

During this course, we will discuss statistical models and techniques beyond classical linear modelling. Following a brief review of the basics of linear regression, we will dive into more advanced topics, such as generalized and mixed-effects linear models. We will further discuss the application of mixed-effects linear models in analyzing longitudinal data. Finally, in an attempt to move beyond linearity, we will explore extensions of linear models, such as polynomial regression, splines, local regression, and generalized additive models. Throughout the course, the emphasis will be put on concrete applications in clinical and biological data analysis using real world examples.

Audience

This course is intended for life scientists who already use the R programming language and have some basic knowledge of statistics (including statistical tests, correlation, and linear models).

Learning outcomes

At the end of this course, participants will be able to:
* identify the appropriate model to analyze a dataset;
* fit the chosen model using R;
* assess the fit of the model, as well as its limitations.

Knowledge / competencies

The course is intended for people already familiar with basic statistics and R. Participants must be comfortable with topics such as hypothesis testing, correlation and linear models, and must have a prior knowledge of the "R" language and environment for statistical computing and graphics. Participants who have already followed the SIB course "Introduction to statistics with R" or an equivalent course, and have used its content in practice should fit this prerequisite.

Before applying to this course, please self-assess your knowledge in stats and R to make sure this course is right for you. Here are 2 quizzes:

- Quiz: Introduction to Statistics

• "Introduction to R" self-assessment for the advanced statistics course

Technical

You are required to have your own laptop, with at least 4 Gb of RAM, "R" v4.2.0 and "RStudio" 2022.02.2-485 software installed. More information about the packages needed will be provided in due time.

Brief course programme

• Monday: simple and multiple linear regression (theory, diagnostics, and model selection)
• Tuesday: generalized linear models (binary data, proportions, and counts)
• Wednesday: mixed-effects linear models, longitudinal data analysis
• Thursday:smoothing and generalized additive models
