» If the irrelevant post hoc power is always 98%, I suspect a flaw in the software (or SAS macro).
» If it is always higher than the one used in sample size estimation it may be a miscalculation – ineradicably “popular” in Indian CROs (see this post). Revise your procedures

I'm sorry, I mean to say always it is coming in the interval 95 to 99 and some times 100 ofcourse one time only, some times we are getting less power on 80s but very less times.

On two occasions I have been asked,—“Pray, Mr. Babbage,
if you put into the machine wrong figures,…
will the right answers come out?”

I am not able rightly to apprehend the kind of confusion of ideas
that could provoke such a question.    Charles Babbage
