OpenMx version 2.7.10 is now available through CRAN [1].
New features, performance improvements, and bug-fixes in OpenMx v2.7.10 include the following:
mxRobustLog()
[4], has been implemented. mxRobustLog()
returns the natural logarithm of its argument, unless the argument is zero, in which case it returns -745 instead of -Inf
(see documentation [4] for details). It is recommended for use with mixture models.
mxEvaluateOnGrid()
[4], has been implemented. It is useful for quadrature integration.
omxParallelCI()
[6] now respects locally set mxOptions [7], and no longer unnecessarily redoes the primary optimization (for point estimates).
mxGetExpected()
[8] could fail in cases where one MxModel references a component of another MxModel, when both are submodels inside a "container" MxModel. This bug has been repaired.
mxGetExpected()
[8] now works with GREML expectation [9].
mxGetExpected()
[8] can now provide asymptotic ("infinite-time") covariance matrices for state-space expectations [10].
mxSE()
[11] now safely handles MxConstraints [2].
mxTryHard()
[13] now works with MxModels that use the Nelder-Mead optimizer [12].
mxCompare()
[14] now behaves more sensibly when it is comparing MxModels that have the same degrees-of-freedom.
mxRefModels()
[15] when using WLS [5] with a multigroup MxModel has been repaired.
mxAutoStart()
[16] now works better with multigroup models.
Mac users of R v3.4 can download a "bleeding edge" developers' build of OpenMx from here [17], but note that the bleeding edge build is not a stable package release and is only minimally tested. Furthermore, it does not work on Mac OS X 10.11 "El Capitan."
