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.

• confidence interval optimizations now jitter if they can't get started
• added error checking for dimensions of expected means in ML + FIML objectives
• check for missing observed means when using (optional) expected means in ML
• added citation("OpenMx") information

Release 0.4.0-1313 (June 09, 2010)

• fixed bug in calculation of confidence intervals around non-objective values
• checking for partial square bracket references on input
• fixed error reporting for non-positive-definite covariances in FIML
• implemented initial sorting-based speedup for FIML objectives
• added 'No Sort Data' to mxOptions()
• eliminated getOption('mxOptimizerOptions') and getOption('mxCheckpointOptions')
• added getOption('mxOptions')
• error messages for illegal names provide function call information
• added 'estimates' column to confidence intervals in summary() of model
