Statistical commands are e-class or r-class but not both. Any r-class
results visible through -return li- after an e-class command are left
over from some previous r-class command, and vice versa.
-regress- is an e-class command. The coefficients are in e(b).
See the manual entry for -regress- for details; otherwise here is an example.
