OpenMx 0.4.1

This time was have a twofer for you. We were getting prepared to release version 0.4.0, and we detected a few bugs before the release of 0.4.0. So below is the changelog for OpenMx 0.4.0 and 0.4.1. This is mostly a bug fixing release. So we recommend upgrading to this version. There are a few performance improvements. Most notably there should be an improvement to our users running FIML models with ordinal data. Expect to see more performance improvements as we get closer to the 1.0 release.

  • fixed bug in calculation of confidence intervals around non-objective values
