» TIE which is significantly >0.05 in red (limit of the binomial test 0.05036). I don’t understand why in some scenarios the TIE is lower with a minimum n2.
» Counterintuitive.
I'm quite sure: This is because of the simulation error. The differences of the TIE without and with min.n2 are so small. See the last column above.
Any try with a different seed of the random number generator may and will change the comparison.
Edit: Removed irrelevant columns for clarity. [Helmut]
