RegisterDenmark Curiosa (1 in 90% CI in 0.8-1.25) [Power / Sample Size]
Dear zizou,
what a laborious task!
One minor comment to your code:
The number of sims you used (
Another comment to the Danish requirement:
Already in the early days of the evolution of (bio)equivalence tests it was dicovered that another construction of the CI may be used, namely
This construction of the CI always contains GMR=1 and corresponds - like the conventional CI - to a size alpha TOST.
This observation makes the Danish requirement statistical nonsense.
Unfortunately this alternative CI hasn't got further support in the history.

what a laborious task!
One minor comment to your code:
The number of sims you used (
1e4 as far as I could see) is a little bit low. Especially if you come into regions with power <=0.05.Another comment to the Danish requirement:
Already in the early days of the evolution of (bio)equivalence tests it was dicovered that another construction of the CI may be used, namely
CI+ = (low, 1) if high is < 1
CI+ = (1, high) if low is >1
CI+ = (low, high) if low is <=1 and high is >=1
low and high are the conventional confidence interval limits.This construction of the CI always contains GMR=1 and corresponds - like the conventional CI - to a size alpha TOST.
This observation makes the Danish requirement statistical nonsense.
Unfortunately this alternative CI hasn't got further support in the history.
