Then came an answer today! Nick's point about the random number generator is taken. It also seems that a model that fits some times and not others is inherently fragile. If true, this might explain the lack of reproducibility. http://interopix.com/stata-error/stata-error-r-303.php

Single imputations of missing values result in misleading underestimation of the variation in the data, which in turn leads to incorrect estimates of the models built on them. If the results are very different you should be concerned. If your hypothesis is of the **form "antecedent** X is associated with outcome Y" and if education is associated with both X and Y, then omitting it will cause bias.

Remember also that for the purposes of any regression command, an observation only counts if it has non-missing values for every variable in the command. http://www.stata.com/statalist/archive/2009-09/msg00178.html The syntax didn't run, but when I added 'break' it worked without an error!

I read the article by Ai and Norton (2003) which clearly points out that the calculation of marginal effects in the framework of nonlinear estimation techniques such as ordered probit is http://interopix.com/stata-error/stata-error-r-601.php I have already e-mailed Tristan Zajonc, the author.

They cannot be used directly to estimate potentially interesting quantities such as the population standard deviation. mac li > > to see what Stata is holding in local > macros. I very much doubt whether the fact that you have two different versions of Stata installed is at all problematic for your purpose. So I would certainly agree with using your single-imputation approach as a first step, and getting the multi-level model set up, running, and correct using that first.

Since your variable educ now contains imputed values, it is not surprising that some of them are out of the range of the original variable. I had to install version 10 all over again and update it to 10.1 as -openirt- was set to run in version 10.1. -openirt- ran smoothly in version 10.1. The problem is that hettest isn't designed to run after areg. useful reference So I was thinking more about issues of statistical power.

How does it work?
