Currrntly I'm doing masters thesis on migration using count model.poisson and neg.binomial have no problem but when i try zeroinflated and hurdle model some pridctor variable shows error in r software.....like computationally singular
as.matrix.fit$hessian...
So how I can fix the problem and include the variable in analysis???

@katxt over a year ago you helped me to analyse a casino slot dataset in this post: http://www.talkstats.com/threads/which-probability-distribution-do-i-use-for-this-and-how.69605/

Ive come back looking for the charts you did for me. Hopefully you remember the thread and by any chance do you still have the charts?
