Shyam, I have found Dave Atkin's tutorial to be very helpful in a situation
that may be similar to the one you describe. I was at a loss to understand
the estimated coefficients in poisson regression before reading it. It seems
to be behind a paywall ($11.95), though it was not the last time I checked.

Hi all

I am using generalized linear mixed model fit by the laplace approximation
(family poisson) to analize my data. I have seed number (dependent variable)
as a function of study site in two lations in two countries. i ran the model
in R . But i need some assistance to interpret my data. Any source,
reference or result of previous work welcome.

thanks in advance
