Dear Detlew,

❝ what do you think is a reasonable assumption about the distribution of the metric AUC*k?

Since both are lognormal, their ratio should be lognormal as well. I trust here Martin; will meet him in the evening and ask again. Furthermore, the distribution of values per se is not important, only the residual error.

One of my 4-period full replicate studies (143 subjects, Method A)

❝ Do we have to throw away our evaluation of BE studies assuming log-normal distri of the metrics AUC and/or Cmax?

Not at all – if they passed.  Too bad if they failed and would have passed with AUC·k…
