GMM estimation

Hello! I have a problem and I although it may sound stupid I do not know how to work it out. I am triying to estimate an equation using GMM and I need to specify it without a dependent variable, I just turned from tlo=C(1)*b+C(2)*w into tlo-C(1)*b-C92*w (for example) but I get the message no coefficents specified. I need to have the estimation computed stating at dependent variable: implicit equation.
Thanks.

You appear to be missing parenthesis around C(2) in

Sorry, this is not the pb. In eviews I wrote it well, I didn t copy paste it from eviews. So this is not the pb, I tried again now and I have the same message.

Try running this program:
Code: Select all
create u 1000
series tlo=nrnd
series b=nrnd
series w=nrnd
series z1=nrnd
series z2=nrnd
equation eq1.gmm tlo-c(1)*b-c(2)*w @ z1 z2

Same message. I seems very strange because I read in eviews guide help and I followed the same steps.:(
