Dear Helmut!

❝ ❝ TXH for educating me.


❝ Come on! Didn’t I got the paper from you?


Not the Liu et al. which I don't have AFAIK.
Not so sure since lately I forgot things every now and than, seems aging or too much beer :-D.

❝ ...

❝ ❝ BTW: How did you arrive at the histograms of the sample size?


❝ Crude example:

library(Power2Stage)

  N <- as.numeric(power.2stage(CV=0.3, alpha=c(0.001, 0.0413), n1=24,
       npct=seq(0.001, 0.999, 0.001), print=FALSE, details=FALSE)$nperc)
  hist(N, freq=FALSE)
  abline(v=c(median(N), mean(N)), lty=c(1, 3))


Wow! That made me dumbfounded! Clever, clever.
:clap:

Regards,

Detlew

Scientists often have a naïve faith that
if only they could discover enough facts about a problem,
these facts would somehow arrange themselves
in a compelling and true solution.    Theodosius Dobzhansky
