Hoe to get RESIDUAL VARIANCE in logistic regression using lmer
Hello everybody, using the lmer function, I have fitted the following logistic mixed regression model on an experimental data set containing one fixed factor (Cond) and three random variables (Sito, Area, Trans): > model<-lmer(Caul~Cond+(1|Sito)+(1|Area)+(1|Trans), data=dataset, > family=binomial) this is the output: > summary(model) Generalized linear mixed model fit by the Laplace approximation Formula: Caul ~ Cond + (1 | Sito) + (1 | Area) + (1 | Trans) Data: dataset AIC BIC logLik deviance 548.7 57...
