Glmer binomial assumptions
WebJul 10, 2024 · The same function can be used for Poisson regression, but it does not work for quasipoisson overdispersed data. However, within lme4 there is the function glmer.nb for negative binomial mixed effect. The syntax is the same as glmer, except that in glmer.nb we do not need to include family.

Web6.1 - Introduction to GLMs. As we introduce the class of models known as the generalized linear model, we should clear up some potential misunderstandings about terminology. The term "general" linear model (GLM) usually refers to conventional linear regression models for a continuous response variable given continuous and/or categorical predictors. WebOct 23, 2024 · This is because you are using the binomial family and giving the wrong output. Since the family chosen is binomial, this means that the outcome has to be either 0 or 1, not the probability value. This code works fine, because the response is either 0 or 1.
