Hello !! II'm trying to test for my fixed effects using an lmer with quasipoisson errors.
Since my lmer model is corrected for overdispersion using this kind of errors, I should use during model simplification in my Anovas *F test *and not *Chi square test* to compare two models. So I write: > anova(model,model2,test="F") but R keeps performing a Chi square instead of the F test I want... Any ideas why ? Thank you very much !!!
