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?

Pass or fail!

Most scientists today are devoid of ideas, full of fear, intent on
producing some paltry result so that they can add to the flood
of inane papers that now constitutes “scientific progress”
in many areas.    Paul Feyerabend
