lmer{lme4}, poisson family and residuals
Hello,
I’m trying to fit the following model:
Dependent variable: MAXDEPTH (the maximum depth reached by a penguin during
a given dive)
Fixed effects: SUCCESSMN (an index of the “individual quality” of a bird),
STUDYDAY (the day of the study, from -5 to 20, with 0=Dec 20), and the
interaction SUCCESSMN*STUDYDAY
Random effect: BIRD (the bird id, as each bird is performing several dives)
Using lmer with a poisson family, I got a huge amount of warning messages:
> reml.res <- lmer(MAXDEPTH~SUCCESSMN*...
