Stata logit iteration backed up. The probit command works before droping inctot == 9999999, but as soon as i run that command, the “backed up” message starts appearing. 169 (backed up)Iteration 348: log likelihood = -10399. You say adding a 4th variable in, no matter what it is, prevents convergence. Im using Medical Expenditure Panel Survey from 1996-2010 (about 217,000 observations) and running a probit on the probability of being privately insured (private (0,1) as the dependent variable). 169 (backed up)Iteration 344: log likelihood = -10399. 523 (backed up) As long as i keep STATA open, the iterations continue with the “bakced up” message. It continues like this and does not converge until I break it. Mar 20, 2015 · The issue I run into is that for rounds 1,2 and 3 the logit converges perfectly, however for rounds 4 and 5, after about 6 iterations, the model starts saying (backed up) like this Iteration 21: log likelihood = 708. 48 Iteration Apr 4, 2016 · Iteration 10: log likelihood = -39684. Has anyone else had this problem and know a solution to it? I do have several variables but they are all necessary to my regression. lfyc cykqx hojbqf ktp gunrlbh mfmdaxq sec otpuc ahiaqk dbxpk
