Equivalence testing - is there evidence of similarity?

This May, we are going to explore equivalence testing - a method that helps us look for evidence of similarity. We will introduce univariate equivalence testing using the R package TOSTER and look at multivariate equivalence testing using the package ecopower. Check out the slides and code here!

glmmTMB: the flexible and fast package for fitting generalized linear mixed models

February's Eco-stats lab was about the R package glmmTMB for general linear mixed models. glmmTMB is considerably faster and more stable than lme4 while retaining the same syntax as lme4. It offers more distributions such as negative binomial or Conway-Maxwell-Poisson distribution for overdispersed counts and provides extensions of GLMMs. Check out the slides to see some examples of what can be done.
