Hi! I have results from a survival analysis using PROC LIFETEST in SAS 6.12. I would like to calculate a post hoc power of my log-rank test. Is there an example of a SAS program (macro) that can do that so I may use an output dataset containing all my data? If not, how can I do that power calculation? Do you have a reference? Thanks for your help.
