P values in lmer
WebThe lmerTest package provides p-values in type I, II or III anova and summary tables for linear mixed models ( lmer model fits cf. lme4 ) via Satterthwaite's degrees of freedom method; a Kenward-Roger method is also available via the pbkrtest package. Model selection and assessment methods include step , drop1, anova-like tables for random ... Weblmer could just as easily report the same kinds of p-values but doesn't for valid reasons. I guess it's the comment that there are any "real" p-values here that bugs me. You could argue that you can find one possible cutoff, and that any reasonable cutoff is passed. But …
