Hi all

I have a regression equation
y = bo + b1.x1 + b2.x2 + b3.x2^2 [simple OLS regression]

I need to estimate the standard error of [b2 + b3.x2].

The closest I have come is the nlcom command, which I suppose  
estimates the variance of non linear combinations of estimators only.

Thank you

Regards
Vatsalya
