Dear All, I'm a relative novice in R, with some experience with S-plus and quite a bit in SAS. In R and S-Plus, I've primarily worked with Frank Harrell's Design and Hmisc libraries. I have R 2.3.1 for windows (XP) installed.
I have a project coming up in which the outcome will be recurrent events. There will be right censoring and likely to be a good stack of 0s on the left. In searching the R archives, I came across the gcmrec package, which looks like it will estimate the models I might be interested in. My question is whether anyone is aware of work done on sample size planning for these models? I came across a meeting abstract for a paper that apparently presented some SAS code for power estimation, but I haven't had any luck contacting the authors. Does anyone have any experience with this issue or pointers to where I might do some reading on this topic? Of course, any thoughts on the approriate model would also be more than welcome. Thanks, Mike Babyak ______________________________________________ [email protected] 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.
