Dear earlybird!

❝ you should take into considerations a statistic course for regulators ;-).


Well, I was asked by regulators from Austria and Saudi Arabia a good while ago. They were shocked by the fee. :-D
I performed a workshop in Turkey; was anybody of you asked for power (in other words, did I succeed)?

❝ As long as the regulators ask for the a-posteriori-power, …


Do they still? Which ones? I know that this was a hobby of regulators from Greece more than a decade ago. The last request I have seen came form Malaysia. They were asking for ‘Two One Sided t-Tests Total Probability’, ‘Anderson-Hauck Procedure p-value’, ‘Power of ANOVA at 20%’. By coincidence (?) these are the last lines of WinNonlin’s standard output. ;-)

❝ … you should be able to calculate it :confused:.
