Hi statalists,
I've tried to run the rollreg function on some simple data of mine and
always got a
option / required
r(198);
error message.
Being slightly frustrated after a little while I tried the illustration
provided by Baum (2006) and stumbled upon the very same problem, i.e.
. webuse wpi1, clear
. g t2 = t ^2
. rollreg D.wpi t t2, move(24) stub(wpiM) graph(summary)
option / required
r(198);
Does anyone have a clue what (probably very obvious lapse) I am missing
here? Thanks so much.
Ben
