Dear all,
I did a maximum likelihood and I constrained one parameter to be
between zero and one, in this way:
gen double `am'=1/(1+exp(-`a'))
and then I generated the standard error using the delta method.
Now I want to constrain the parameter to be between 0.07 and 1.
How can I do this?
Thank you very much
Best,
Bea
