Dear D. Labes,

❝ ❝ Sometimes I forget the true country of the brave and the free - Canada...

❝

❝ Brave and free already since a long time ago regarding their outstanding handling of C_max :ok: .

Not to see the wood for the trees!

Though I quoted Eric correctly (the sentence is already given in Health Canada's Notice for Industry for rapid onset drugs from June 2005) I overlooked that nobody asks for a confidence interval. :-D

So only the mean should lie within 0.8-1.25.

Going back to my examples:
first post
Example 1: nonparametric t_max BE, parametric AUC_Reftmax BE
Example 2: nonparametric t_max not BE, parametric AUC_Reftmax not BE
second post
Example 3: nonparametric t_max not BE, parametric AUC_Reftmax BE (though close: GMR 81.2%)

I guess the 'Canadian way' would be an alternative for EMEA's 'statistical experts' not accepting dreadful nonparametrics - and dealing with high variability whilst not loosing their faces.
Hopefully somebody suggested it to EMEA; I realized it just today (one week too late) and suggested in my comments keeping the nonparametric method. :rotfl:
