Hi Forum,
We are planning a XO BE study to support a manufacturing change, and have only data from a single administration (from which we extracted %CV).
In order to calculate sample size, do I need information regarding expected correlation between PK parameters in period 1 (test) vs period 2 (ref)? What would be a reasonable assumption when there is no prior data?
Thanks, Laura

Many people tend to look at programming styles and languages like religions:
if you belong to one, you cannot belong to others.
But this analogy is another fallacy.    Niklaus Wirth
