Hi Hötzi,

» Nope.

For such cases we are setting logscale to False, right?
PowerTOST says about theta1: "Defaults to 0.8 if logscale=TRUE or to -0.2 if logscale=FALSE. "
So as I read it, when logscale=F theta1 defaults to -.2 or we set it to something negative. This is how I think Hauchke's f1 and theta1 get confused.

I will read up on the other stuff. Still not sure how to derive the CI. it is a really interesting problem, though. Feels like going back into a discussion which was closed decades ago before I knew anything about BE :-)

Thanks PharmCat for the ref. below.:-)

I could be wrong, but...
