Is AIC calculated incorrectly in lmer? It appears as though it uses
AIC = -2*logLik - 2*#parms, instead of -2*LogLik + 2*#parms? Below is
output from one of many models I have tried:
Generalized linear mixed model fit using PQL
Formula: cswa ~ pcov.ess1k + (1 | year)
Data: ptct50.5
Family: poisson(log link)
AIC BIC logLik deviance
