Dear saimsc!

❝ Can you please let me know the formula for Inter subject variability in SAS/Statistics


See here. Counter question: What for do you need CVinter (between subjects)? In sample size estimations you need CVtotal (parallel groups) or CVintra (cross-over studies - within subjects); CVinter is irrelevant in any case.
