This was cross-posted to StackOverflow (broken URL: http://stackoverflow.com/questions/16046726/ regression-for-a-rate-variable-in-r ), where I made that suggestion. I don't know that cross-posting to r-help lists and StackOverflow is anywhere expressly forbidden (cross-posting *among* r lists is ruled out in the Posting Guide), but I'd prefer people didn't (because of this kind of wasted/duplicated effort). ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
