Thanks for pointing out the aod package and the beta-binomial logistic models Renaud. While I see how betabinom could be applied to some of our other analyses , I don't see how it can be used in our habitat selection analysis where individual locations are coded as 0 or 1 rather than

help We want to estimate the number of caribou in Jasper. We recently conducted an aerial survey and saw 70 uncollared caribou and 8 of 11 collared caribou. We want to estimate the number of caribou in this population with 95% confidence limits. Gary White uses the hypergeometric distribution
