Hello, Stata world. I'm using -pwcompare, effects- after regression. The command produces point estimates and confidence intervals, but I'm wondering if there is a way to estimate a standardized effect size such as Eta squared or Cohen's d for each contrast, which -estat esize- doesn't do.

Code:
sysuse auto
reg mpg weight i.foreign##i.rep78
pwcompare 0.foreign#rep78, effects

Thank you!
