WebbRemember that convergence is rarely guaranteed for non-linear estimates. never converges, it may not be a bug in Stata and it may not be worthwhile letting it run It may that you are not presenting Stata with the data you think you are. before giving up, you should try the following strategies. WebbMy experience suggests that the problem may be due to the number of dummies in the model and/or to the limited IWLS iterations set by default by the software (25 in R). …
