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
