Betreff: st: Regressing and storing residuals in one line.
Hi,
I'm trying to run several regressions (one for each level of a categorical
variable) and store the residuals from each regression in a local macro or
new
variable I could later manipulate. I figured I could use:
bysort category: regress y x1 x2
to run the regressions, but I need a second line of code (predict name,
residuals) to get the residuals when bysort allows only one. Is there a way
around this?
Thanks,
Dani F. Tilley
