There are probably more elegant ways to do it, but this works: sysuse auto corr price mpg rep78 mata C = st_matrix("r(C)") mean(abs(select(vech(C), vech(C) :< 1))) On Tue, Sep 11, 2012 at 9:34 AM, John Antonakis <John.Antonakis@unil.ch> wrote: > I would like to calculate the average absolute correlations of a correlation > matrix.
