» not Detlew but answering anyway.
Thank you for quick reply at every time.
» So why are you not simply using it?
» sampleN.RSABE(CV=0.4, theta0=0.9, targetpower=0.8, design="2x2x4")If you want further information about the arguments and their defaults, type
?sampleN.RSABEin the R-console / R-Studio’s console or consult the online manual.
As this is a replicated study, there are only few articles for calculating the sample size.
There is no clear information about this. So that, I suppose to understand concept through R-program.
I have few more doubts, regarding the terms CVswitch, r_const and pe_constr.
I thought CVswitch=0.30 for both FDA and EMA, r_const=0.25 and 0.760 for FDA and EMA respectively and don't know about the pe_constr.
Kindly correct me if I am wrong...
Thank you in advance.
