st: Simple ML estimation question

[Bulent Uyar <Bulent.Uyar@uni.edu>]

Hello everyone,

I am a stata beginner. Therefore, I apologize in advance for this (what 
must be a very simple) question.

Here is my model:
lny = b1 + b2*lnx1 - ln(15+b3*x2+b4*x5) + e.
e is assumed to be N(0, sigma^2).

I have been trying to code this so I can estimate it using
"ml model lf ...".

How do I code the " - ln(15+b3*x2+b4*x5)" part of the model so I can 
properly express it in the statement
"... `lnf'=ln(normalden(..." ?


Thank you for your guidance in advance.
