CES function

[londonphd]

Hello,

I have estimated the following nested CES function together with its FOCs.

where, rho is the estimated parameter from which the elasticity of substitution sigma is computed as

Now I wonder how I could calculate the standard error of sigma for hypothesis testing on sigma. STATA appears to have a procedure for doing this, but I prefer using Eviews. Can anyone please help?

In the equation window View/Coefficient diagnostics/Wald

The if rho is the coefficient c(3) (or whatever)

1/(1-c(3)) = 0
