Hello all,
I have a big data set and am trying to run regressions
on various combinations of sections. Is there a way to
do this w/out having to drop irrelevant observations
every time?
Example:
A y1 x1
A y2 x2
B y3 x3
B y4 x4
C y5 x5
C y6 x6
Running y on x only for the A section without having
to drop all B and C observations. Then regress y on x
for AC, for AB, etc.
Thank you in advance!
T.J.Volant
