[R] count data with nested mixed effects

2006-11-10 Thread kohn
Dear R-Pros, I have count data in which 6-10 points are nested within 17 larger units (which are nested within 3 larger-still units) plus a number of covariates. It could be nested ANCOVA but for poisson family. Could someone kindly advise me 1) if lmer is the correct function for the analysis?

Hi Deborah, A very good source for hands-on information on mixed models in S is: Mixed-effects models in S and S-PLUS by Pinheiro and Bates Incidentally, it's available in your university's library http://toroprod.library.utoronto.ca/uhtbin/cgisirsi/2XfWcMI0Ns/ROBARTS/140640080/2/1000 I
