Hi,
I am performing a Zero-inflated Poisson and Negative Binomial GLM using R (my data did not meet the conditions for a 2 way-ANOVA, and the GLMs with Poisson and Negative binomial distributions gave an overdispersion (7)). So I went to the zero-inflated solution since my data has a lot of zeros. The issue is while the analysis run well, I have some NAs in the outputs (only in the treatments that have only zero and I don't know if:
1 . this could be a problem for the interpretation.
2 . the outputs are valid.
3 . if not, what kind of analysis I can do?
I am sorry if my question is not clear. I put attached the data in case this make it clearer.
Thanks in advance.
