Thank you, Anderson.

Since PALM returns both t stat and degrees of freedom, I calculated Cohen's d using

(N1+N2)×t-stat/(sqrt (dof×N1×N2)) using N for my 2 groups but this isn't the same as returned by Cohen's d.csv. I will greatly appreciate if you could comment on why that would be the case.

Thanks

Hi VM,

It's the coefficient of variation: https://en.wikipedia.org/wiki/Coefficient_of_variation

Actually it's a bit more general than the Wikipedia article suggests. It's here the reciprocal of Cohen's d.

All the best,

Anderson

Hi, Anderson,

What does *_cfvar* signify? It is returned when --saveglm is on.

Thanks
