Andr�:
The best advise I can give you is to buy "Maximum Likelihood Estimation with Stata" by William
Gould, Jeffrey Pitblado, William Sribney, Stata Press. (http://www.stata.com/bookstore/mle.html or
your local distributor (faster shipping if you live half way across the world and they have it in
stock)) It is very helpful if you want to use -ml- to maximize your own likelihood function. It is
clearly written and contains lots of example code.
-ml- is not as difficult as it may first seem, but if you have no idea where to start, than what
you want to do without the book is probably too difficult. Ones you get the book built your
program step by step, e.g. first make a program doing a probit, than a bivariate probit, and than
add the censoring.
