Model D: Allowing unemployment to have both fix and random effects.
We thank Hemant Kher for providing the Mplus code for this example.
NOTE: The results obtained from Mplus do not match those shown in the text. Regarding these differences, Professor Bengt Muthen says:
"Notice that there are some numerical issues with the model - the variance-covariance matrix of the random effects is singular. Just a little more information about Mplus. If you add the technical option output:tech8; you will see the details of the convergence process. The default algorithm EMA quickly reaches the ML estimates but fails because the variance covariance matrix for the random effects is singular. At that point Mplus switches to the EM algorithm which slowly approaches the singularity, but Mplus will deliberately avoid the full convergence to avoid the singularity. In this part of the algorithm the solution is driven by the logcriterion convergence criterion. So essentially all software packages differ because the ML solution is inadmissible, so they report their own version of "approximately" ML solution."
