RegisterBigamist [Power / Sample Size]
Dear Helmut!
They would call me "Bigamist" and send me to prison in many countries. And I think my spouse wouldn't be very amused if I convert to a Mussulmán in my old days
.
But anyhow: Thanks for the flowers.
I'm not quite sure if you are right here. In simulating 2-stage adaptive designs the power/sample size steps may contribute considerably to the computation times. Thus they may stay the show-stopper even if we can push on the calculations of stage 1/stage 2 BE by the ideas behind power.scABEL() or behind the code inthis post.
But lets see ...
2-stage design combined with RSABE will have another drawback: Where is the point for simulations which represents alpha
? Simply GMR=1.25 (or whatever BE limit applies) surely not.
Eventually power.scABEL() will help to explore.
❝ Do you want to marry me? The community will love you for that!

❝ Opens even the door for two-stage simulations where the intermediate power/sample size was the actual show-stopper.
