Dear all,
It seems that the newest version of lme4 (0.999999-0) now provides P values in the summary tables.
Given the many previous discussions about the derivation of P values in lmer, I was just wondering
how "safe" it would now be to use these values (and how they´re calculated). I guess they´re just
taken internally from a call to glm?
Example:
##
gm1 <- glmer(cbind(incidence, size - incidence) ~ period + (1 | herd),
family = binomial, data = cbpp)
summary(gm1)
coef(summary(gm1))
##
Many thanks,
Christoph
