st: how to perform Wald tests with NLS
I am using nl command to estimate a nonlinear specification. In short, my model is:
and my output looks like
dgr5y Coef Std. Err.
C0 .02 .0083 etc.
b0 .06 .2828 etc.
b1 1.2 .89 etc
b2 .93 .282 etc
C1 .97 .008 etc
C2 .16 .008 etc
and I want to test C1=C2. I have tryed to use the test command after running my programs (both nl and ml) but it didnt work. If i type
it doesnt work althoug it perform "test C1" (the h0 is C1=0) but not "test C1=2". What can i do? I tryed two things. first I regressed
and I did "test C1".
In shorth, I want to know
1- why test didnt work?
2- It is ok to do the regression with x5=(x3+x4) and "test C1"?
