I was experimenting yesterday with a binomial make.link option for estimating student t binary response models, tentatively called gossit, and I noticed eventually that the R qt function doesn't like df < 1. Vaguely recalling that Splus didn't seem to mind such weirdness, I checked on our soon to be defunct Splus6.2 and sure enough, it produced plausible answers instead of R's NA's. Of course, I have no way of judging the quality of these answers, but I'm curious about whether someone has already looked into this can of worms.
