Dear Helmut!

❝ With roundit=T I got 0.033605.

Me too.

❝ Same value if I switch lines 65–66 to R’s round(). With my original code I got (R’s rounding) 0.033786, but run-time was ~30 minutes.

Your observation that cround() and round() work equal if rounded to 4 decimals.

❝ BTW, couldn’t figure out how to modify the code for imbalanced sequences.

Described in the question for unbalanced designs.
Based on this:

power2.TOST(CV=0.3,n=c(4,7),theta0=1.25)

[1] 0.02718537

set.seed(123)

power.sim2x2(CV=0.3, n=c(4,7), GMR=1.25)

[1] 0.027217
