Dear all,

I'm trying to estimate a sample size for two-sample comparison of means
using the command sampsi.
The study is to test for a difference in effectiveness of 0.5 between
two groups, assuming a sd(1.4)
Is there any way to change the normality assumption? Is there another
way to estimate sample size?
