Hello, my question is fairly involved but I would appreciate any help anyone
can offer. I would like to draw 500 random samples of size 20 from an
exponential distribution with 7 different means. (total 3500) Next, I want
to test the equality of the survival distributions within each group of 7
(only 2 at a time) using logrank and Wilcoxon. What I want to end up with is
the number of times the null hypothesis is rejected in 500 trials. Basically
all I need in the output is that number or just the p-values so I can count
them. The comparisons within the 7 different means would be group 1 vs 2, 1
vs 3,........, 1 vs 7. I have the manuals here at home so feel free to cite
them. Is this possible to do in SAS? Thank you in advance for any help.
