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

Most scientists today are devoid of ideas, full of fear, intent on
producing some paltry result so that they can add to the flood
of inane papers that now constitutes “scientific progress”
in many areas.    Paul Feyerabend
