My guess is it won't and that Nick is correct. Like Maarten always recommends, start with a really simple model and then gradually make it more complicated. WebWhere one fails, another may succeed. Furthermore, what is appropriate at the initial values may not be optimal near convergence. -difficult- is said to be useful when the optimizer complains "not concave". If your problem converges in Stata N, but fails in Stata N+1, that may just mean that Stata N is better at your problem. list of 3rd person pronouns
