Hi, I have a very similar problem... In some sites, counts data0 In the other sites, counts = 0 I already applied zero inflated models with the zero-trick (Martin et al 2005 in Ecology letters), but I would like to use truncated distributions (Poisson and negative binomial) to model my counts in

I am using a binomial mixture model to estimate abundance (N) and detection probability (p) using simulated count data: -Each site has a simulated abundance that follow a Poisson distribution with lambda = 5 -There are 200 simulated sampled sites -3 repeated counts at each site - only 50 percent
