Onsite course: Advanced Multivariate Analysis - Integrating Classical Techniques (PCA, RDA, CA, CCA) with multivariate GLMM. Monday 13 - Thursday 16 May 2024. Hotel de Nieuwe Wereld, Wageningen, The Netherlands
This is a hybrid course; you can either attend in person or join simultaneously via Zoom.
Course flyer
This course offers a journey through classical multivariate analysis techniques and advances into recently developed tools for multivariate GLM and GLMM.
We start with classical multivariate techniques like principal component analysis, redundancy analysis, correspondence analysis and canonical correspondence analysis. We then continue with generalised linear latent variable models (GLLVM). A GLLVM is a GLM (or GLMM) in which multiple response variables are analysed simultaneously, while allowing for dependency between the response variables and also between the observations. We will discuss extensions of GLLVM that allow for constrained latent variables (concurrent ordination) and spatial and temporal dependency structures.
This is an applied and non-technical course that focuses on the practical implementation in R.
Pre-required knowledge
Participants should be familiar with data exploration, linear regression and basic GLM and GLMM (i.e. Poisson and negative binomial GLM) in R. The course website contain revision/preparation material with on-demand videos covering these topics.
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, accessible for 12 months, facilitates interaction on course content between instructors and participants after the course.
