Hi all, Can an exact Poisson regression be computed with R, instead of using the standard (glm) Poisson using maximum likelihood?
I am working with a collegue in a project, and I'd like to reproduce his method, if not his results. He uses Stata, particularly the expoisson function (https://www.stata.com/help.cgi?expoisson) in order to compute the exact Poisson regression, relevant for small samples. expoisson fits an exact Poisson regression model, which produces more accurate inference in small samples than standard maximum-likelihood-based Poisson regression I know about exact Poisson tests (https://stat.ethz.ch/R-manual/R-devel/RHOME/library/stats/html/poisson.test.html), but it does not allow to include offset. So, is there some way to reproduce exact Poisson regression with R? Thanks!
