Dear all,

I want to estimate a system that look like the following:

Y1 = beta0 + X1 * [1 - exp( - beta1 * 5) / 5] + beta2 * X2 + bea3 * X3

I know that it's possible but I don't know how to do it. Does anybody know
any paper or other material that could help me?
So far I estimated only the pooled data set using the -nl- command, but my
dataset is a panel so I'd like to estimate the beta coefficients dividing
the sample periods into subperiods and then running a -sureg-. I only know
how to do it with a linear regression.

Thank you
