I'm using the following equation in a nonlinear regression:
LnVol=AEXP(-a1(TV+LAG(TV)/10)) + BEXP(-b1TV_Net) + Baseline
I receive a warning for every line: "Illegal Lag"
Why am I receiving this warning message?
It is not easy to determine the cause of this without seeing the rest of the data / script. To resolve these sorts of things try:
Assign the LAG(TV) to a variable and then use that within the command - see if the error repeats.
