Dear d_labes,

❝ Simulate with ratio 1.25 and a CV and count BE accepted will give you the overall alpha. Right?

❝ Save if BE was accepted (or not) in stage 1 or stage 2. Counts of BE accepted will give you the alpha's, I think.

Thanks for this suggestion.
If I use n1=36 CV=.3 and T/R 0.8 or 1.25 then the % of acceptance goes towards 0.0294 apparently with 97.1% going into st 2. Potvin et al. mention only 81.1% go into st 2, which to me intuitively seems low.
Bothers me a wee bit; any idea how to proceed?
