Hi,

Sorry for multiple postings. Please consider the following reproducible example:

> grp1 <- rep(1:24, times = 24, each = 1)
> grp2 <- rep(1:12, times = 2, each = 24)
> set.seed(1)
> out <- as.integer(abs(rnorm(576))*10)
> x1 <- out [25:552]
> x2 <- out [49:576]
> mydf <- data.frame(cbind(out[1:528], x1, x2, grp1[49:576], grp2[49:576]))
> names(mydf) <- c("out", "x1", "x2", "grp1", "grp2")

> me1 <- lmer(out ~ x1 + x2 + (x1 | grp1) + (x2 | grp2), data = mydf, family = quasipoisson)
