Great post! [Power / Sample Size]
Dear D. Labes!
THX for calling it "famous".
Right.

❝ […] See for instance Helmut's last famous lecture
THX for calling it "famous".
❝ […] the term sqrt(2/N) has to be replaced by
❝ sqrt((1/n1+1/n2)/2)
❝ which gives different non-centrality parameters and in turn different power values if n1 not equal n2.
Right.
❝ # modified code to account for "unbalancedness"
Great. I guess you are considering updating your package.
