3rd R-in-Grenoble working session

on the November 28, 2019

November 28, from 16:00 to 18:00
The third working session of the Grenoble R community will be "An introduction to Bayesian multilevel models using R, brms, and Stan". Drinks and snacks are served during the second part of the session.

Each month, the Grenoble R-group organizes one working session of 2 hours, on Thursdays, from 16h-18h, at the Imag building.

Everyone is welcome from beginners to advanced R users. Participants just need to bring their laptop. Presentations or tutorials will last 30 to 60 min, on R topics that can be useful to many people, with practical examples. During the second part of the session, specific problems encountered by participants when coding in R will be discussed.

Drinks and snacks will be shared during the second part of the session.


November 28, 2019 An introduction to Bayesian multilevel models using R, brms, and Stan

Bayesian multilevel models are increasingly used to overcome the limitations of frequentist approaches in the analysis of complex structured data. During this session, I will briefly introduce the logic of Bayesian inference and motivate the use of multilevel modelling. I will then show how Bayesian multilevel models can be fitted using the probabilistic programming language Stan and the R package brms (Bürkner, 2016). The brms package allows fitting complex nonlinear multilevel (aka 'mixed-effects') models using an understandable high-level formula syntax. I will demonstrate the use of brms with some general examples and discuss model comparison tools available within the package. Prior experience with data manipulation and linear models in R will be helpful.
