Bioequivalence and Bioavailability Forum

Dear Detlew,

I tried to send a direct messag via Helmuts forum form, but I suspect that it has not worked properly. So, I will give it another try in here as I have two specific questions related to the usage of the R package PowerTOST (which somehow fits to this post I guess) and it would be great if you could shed some light on that.
First, every time I want to use the helper functions CV2se and se2CV I am confused why it is called that way, and not „CV2sd“ and „sd2CV“, respectively. Standard error always reminds me of sd/sqrt(n) or sd*sqrt(2/n) which is not what we want to plug in here...?!
My second question refers to the option „logscale=FALSE“. When logscale=FALSE then I wonder how the argument CV looks like. CV is actually sd/mean, but then one also requires to know something about the mean. A better argument would be the standard deviation and a look into your code reveals that in fact you directly put CV <- se. But when looking into the manual, there is no reference that it will be handled this way and moreover, in the example from sampleN.TOST you write „total CV=20%“ when putting CV=0.2 as an argument. Shouldn‘t it then be „total SD = 0.2“ (not in percent)?

Thank you,
Ben
