We are pleased to announce the official release of OpenMx version 2.7.12. Click here for instructions on how to install the package from our virginia.edu repository. As usual, our repository has package binaries for Windows and MacOS, and source tarballs for Linux/GNU; our builds of the package include the NPSOL optimizer.
Users of Windows and Linux/GNU can also install OpenMx v2.7.12 from CRAN. However, CRAN has not been able to build functioning OpenMx binaries for MacOS since OpenMx v2.7.10. MacOS users can still obtain version 2.7.12 via CRAN, but the Mac onto which you are installing the package must be configured to build it from source. Again, precompiled MacOS binaries are available through our own repository.
New features, performance improvements, and bug-fixes in OpenMx v2.7.12 include the following:
mxBootstrapStdizeRAMPpaths()
, omxBootstrapCov()
, omxBootstrapEval()
, omxBootstrapEvalCov()
, and omxBootstrapEvalByName()
.
mxGenerateData()
now generates data in the compiled backend. This improves performance, and resolves a bug such that generating data for large relational models would fail.
ineqConstraintMthd="eqMthd"
and there are no equality MxConstraints.
mxTryHardctsem()
and mxTryHardWideSearch()
has been repaired. This bug caused those functions to use a default value of 1, not 10, for argument extraTries
.
