Does anyone of you using hurdle model? I am reading a paper which said " Hurdle model removes effect of zero-inflation and over-dispersion in the non-zero observations using a quasi-likelihood", I've checked the help file from hurdle in R, which said differently that"for non-zero obs normally a truncated poisson/NB is used" ... just want to make sure, does it really estimated the parameter by "quasi-likelihood"
