 Simulations?

Hi,

if you don't have analytical solution - look for simulations approach :-D
Simulate the data using known distribution parameters, desired sample size and then use bootstrap technique for evaluation. Repeat it ad-hoc (until the success/failure ratio stabilizes). Then change the sample size and repeat until desired power is reached. Don't forget about SciAdv.

Kind regards,
Mittyri
