More Mixed Models
July 19 @ 3:00 pm - 4:30 pm
Modern Languages Building (MLB), Room 2001A
In the R world, lme4 is a great package for mixed model estimation, and the most widely used for such models. For standard settings, few tools will do the trick as easily or as quickly, and because of that, its approach has been emulated in other packages and statistical programs. However, that ease and efficiency comes at a price of being able to do more complex models, so at some point you may need to switch gears. This workshop will demonstrate other ways to potentially get what you need.
Demonstration will (potentially) include the following, along with some discussion of strengths and/or drawbacks to use.
glmmTMB: heterogenous variances, autocorrelated residuals, zero-inflated models
rstanarm, brms: bayesian approaches
mgcv: additive effects, robust models, big data
statsmodels: in case you’re in the Python world.
This workshop assumes basic familiarity with mixed models, and familiarity with R, especially the lme4 package. However, this is a brief demonstration with a simple goal of bringing about awareness of other useful tools, so one can simply attend to hear about them.
