Hi,
Can anyone advise me on model selection in glm with a zero truncated
poisson distribution?
I have used a the command vglm in the vgam package to analyse the data with
pospoisson specified as the family and I have evaluated alternative models
with a log-likelihood test. I am not sure if that the test statistic will
follow the chi-squared distribution, however.
My data is on seeds per fruit (minimum 1) in different experimental
treatments and different densities of plants.
Regards,
James
