    count data with no zero counts, Poisson?




    Well I appear to have zero deflate data. I will likely treat it as multilevel with clusters, but I was wondering if there was a count approach (e.g., Poisson) you can use on this type of data? So everybody has at least a count of one.

    What is the range of values you're seeing?

    Mostly 1s and 2s a few 3-5s, with very few with higher counts. Haven't graphed but probably right skewed with no real left tail. Sample size, summed count total about 1000 and maybe 700 unique individuals.

    There is a zero-truncated poisson distribution that is fairly well known.
