This course offers an introduction to generalised additive models (GAMs), linear mixed-effects models, generalised linear mixed-effects models (GLMMs), the combination of GAMs and GLMMs, and also includes examples of GAMMs applied to spatial and spatio-temporal data.

The course begins with a review of multiple linear regression, followed by a non-technical introduction to GAMs. Through a series of exercises, we demonstrate the application of GAMs to accommodate non-linear covariate effects.

The second part of the course introduces linear mixed-effects models, which are suitable for data with complex structures, such as observations from clustered or hierarchical sources (e.g., multiple measurements from the same subject). These models extend traditional models by incorporating random effects to account for the non-independence of data points.

Once familiar with mixed models, we will integrate them with GAMs, resulting in generalised additive mixed-effects models (GAMMs). We will do various exercises using GLMMs and GAMMs.

In the third part of the course, we will apply GAMs and GAMMs to various spatial and spatio-temporal datasets. Throughout the course, we will utilise GAMMs and GLMMs on different types of data (continuous and count), employing Gaussian, Poisson, and negative binomial distributions.

Pre-required knowledge
Working knowledge of R, data exploration, linear regression and GLM (Poisson, negative binomial). This is a non-technical course.

1 hour face-to-face
The course includes a 1-hour face-to-face video chat with the instructors (to be used after the course). You are invited to apply the statistical techniques discussed during the course on your own data and if you encounter any problems, you can ask questions during the 1-hour face-to-face chat.

A discussion board (access for 12 months) allows for interaction on course content between instructors and participants.
