Introduction to Linear Mixed Effects Models and GLMM with R-INLA

Segunda, 7 Setembro, 2020 a Sexta, 11 Setembro, 2020
Descrição do Curso 

Given the current pandemic of COVID-19, this course was CANCELLED. 






The course begins with a brief revision of multiple linear regression, followed by an introduction to Bayesian analysis and how to execute regression models in R-INLA. We then explain linear mixed effects models to analyse nested data, followed by a series of mixed modelling exercises in R-INLA. Nested data means multiple observations from the same animal, site, area, nest, patient, hospital, vessel, lake, hive, transect, etc. In the second part of the course GLMMs are applied on count data, binary data (e.g. absence/presence of a disease), proportional data (e.g. % coverage) and continuous data (e.g. biomass or distance) using the Poisson, negative binomial, Bernoulli, binomial, beta and gamma distributions. In the third part of the course we show how R-INLA can be used to execute GLMs with temporal dependency for the analysis of univariate and multivariate time series. We will use R-INLA.

• Pdf files of all powerpoint presentations are provided.
• These powerpoint files are based on various chapters from:
     • Zuur, Ieno, Saveliev (2017). Beginner's Guide to Spatial, Temporal and Spatial-Temporal Ecological Data Analysis with R-INLA.
     • This book is not included in the course fee. The course can be followed without purchasing this book.

• You need to bring your own laptop.
• Please ensure that you have system administration rights to install R and R packages on your computer.
• Instructions for what to install will be provided before the start of the course.
• You will be given access to a course website with around 25 fully worked-out R exercises. These are all based on published papers and real data sets.

What if you are not able to participate? Once participants are given access to course exercises with R solution codes, pdf files of certain book chapters, pdf files of powerpoint files and video solution files, all course fees are non-refundable. However, we will offer you the option to attend a future course or you can authorise a colleague to attend this course. For terms and conditions go to:

• Zuur, Ieno, Saveliev (2017). Beginner's Guide to Spatial, Temporal and Spatial-Temporal EcologicalData Analysis with R-INLA.
• This book is available from



Working knowledge of R, data exploration, linear regression and GLM (Poisson, negative binomial, Bernoulli).
