Hi,
It was not clear to me whether you had
repeated observations for groups.
If your data has a grouped structure, for example 4
repeated measurements by subjects, or if the data set has a nested structure,
for example counts of children within school, then lme is the command that you
want to use to account for the grouping structure.

Subject: [S] lme for count data?
Hi,
I'd like to fit a mixed-effects model to my data.
Pinheiro and Bates (2000) write that "These models are intended for grouped
data in which the response variable is (at least approximately) continuous."
My response variable is count data with range from 0-4, mean 1.7, median 2.0,
stdev 0.8, and an approximately normal distribution. Can I use the lme
function for this data?
Thank you,
A.
