I can't seem to use the new restrict after gmm feature. gmm series e = y - x*beta orthog e ; x weights V params beta end gmm restrict beta = 3 end restrict

Maybe b[beta] would be a compromise.

Or the use of b[i] is enforced even in the formulation of the equation (that's what Eviews does [did?]).

I'll think about how we might permit use of the > original (scalar) parameter names for NLS, MLE and GMM. well as I said, b[beta] seems like an ok solution, so if that works already, and with a more informative error message, maybe no need to touch that.
