Hello everybody, I am trying to accommodate the R codes provided by Donohue for sample size calculation in the package "longpower" with lmmpower function to estimate the post-hoc power (asked by a reviewer) of a binary GEE model with a three-way interaction (time x condition x continuous predictor) given a fixed sample size. In other words instead of the sample size I would like to estimate the power of my study.
Could anyone please help me to modify these codes as to obtain the power I'm looking for. I would really appreciate receiving any feedback on this subject. Yours sincerely, Anne ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see 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.
