Generalised Mixed Models :: Environmental Computing

WebFor generalised linear mixed models (GLMMs), we need to use the parametric bootstrap even for fixed effects inference. This is because the p-values from the anova function are quite approximate for GLMMs even for fixed effects. Sometimes the glmer function will give warnings or errors, so I’ve added a tryCatch to this code to handle that.

Normal, Poisson, and binomial responses are the most commonly used, but other distributions can be used as well. Apart from specifying the response, GLMs also need a link function to be set which allows further flexibility in the modeling.

WebPoisson regression is a form of a generalised linear model analysis, similar to logistic regression. However, instead of using a Bernoulli distribution we use a Poisson distribution. For a numeric predictor like … Webue originally to Nelder and Wedderburn (1972), generalized linear models are a remarkable synthesis and extension of familiar regression models such as the linear models described in Part II of this text and the logit and probit models described in the preceding chapter.
