Dear D. Labes!

❝ […] 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. :-D

to judge the value of your contribution;
not just the information that leads to judgment
in one particular direction or another.    Richard Feynman
