❝ Ahoy old simulant!

Ahoy, d_labes, perhaps I should get a contract in Hollywood?

❝ What I'm a little bit curious of is that regardless how big the number of sims is, the power for low sample size does not converge to your 'normal' values (at least for CV=30%) .

❝ (...) I would expect a convergence to the 'exact' values because we simulate data with distributional characteristics that match those for which the exact power formula was derived.

I guess you are right, thanks for pointing it out. And yes absolutely, simulations of this type MUST converge towards the true value with increasing iterations. I will head down in the programming department and punish the perpetrator right away! Nuts. At any rate, I will post a little later a proposal on how to make the Brute Force parts of EFG 2.01 obsolete.

Sorry I did not see your post before. Or should I say, I am sorry the forum admin screwed up, making it impossible to access the forum, thereby putting a halt to rapid progression of the science that works in the interest of the sick.

EM.
