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. Penner
