For those who use ML or any difficult optimum estimator, convergence
can break down for multiple reasons (e.g., poor initial conditions
or multicollinearity in a bootstrap sample). When it does, stata stops.
Is there a way of convincing stata to make a note and keep going?
To possibly avoid the problem in the first place, check out -help
maximize-. In particular, the -difficult- option sometimes helps.
