Hello All, I am interested in estimating a duration model (also known as survival analysis or event-history analysis). I use an economic dataset. In economics terms, the model is "duration model with sample selection (or selectivity)." The time spell variable is only observed for a sample that meets certain requirements so the sample is nonrandom. Does anybody know any R package that can take care of this?
Thank you. Edwin ______________________________________________ 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.
