OpenMx 0.9.0

This is the full feature release of OpenMx prior to the 1.0 release. Any release between now and OpenMx 1.0 will consist either of bug fixes or improvements to the documentation. This release itself contains a few bug fixes (see below). All users are recommended to upgrade to this version. For OS X users running R 2.10 or 2.11, we have changed the BLAS shared library to use libRblas.0.dylib instead of libRblas.vecLib.dylib. We observed some performance deficiencies when using libRblas.vecLib.dylib. There have also been some new sections added to the user guide. The performance suite results are here.

Change log:

  • improved error messages for non 1 x n means vectors in FIML and ML
  • fixed a performance bug that was forcing too many recalculations of the covariance matrix in FIML optimizations.
  • default behavior is to disable standard error calculations when model contains nonlinear constraints
  • improved error messages for NA values in definition variables
  • added error message when expected covariance dimnames and threshold dimnames do not contain the same elements.
  • fixed a bug when mxRename() encounters a numeric or character literal.
  • new chapters added to OpenMx user guide.
  • fixed a bug in -2 log likelihood calculation with missing data
