Hi,
I am trying to program an ML model to estimate Log
Cobb Douglas production function where some rhs
variables have zero values. To make logs defined I am
adding a constant to variables with zeros that needs
to be estimated too (hence nonlinear MLE). The
function looks like:
lnY=B0+B1*lnX1+B2*ln (X2+alpha)+epsilon
where X2 is the variable with some zero values, and
B0, B1, B2 and alpha need to be estimated. I am also
using a constraint like:
constraint 1 `alpha'>0.
My program does not work and I am wondering whether
anybody can help me with this program. I did not paste
the whole program here since it is a little long, but
can send it to those who could help.
Thank you,
