OpenMx
A Structural Equation Modeling package that encourages users to treat model specifications as something to be generated and manipulated programmatically.
Example models which OpenMx can fit include confirmatory factor, multiple group, mixture distribution, categorical threshold, modern test theory, differential equations, state space, and many others.
Models may be specified as RAM or LISREL mxPaths, or directly in matrix algebra.
Fit functions include ML (summary and full information) and WLS.
The stable
branch can be considered our
current alpha release.
An easy way to install the stable
branch is
to use devtools
:
require(devtools)
install_github("OpenMx/OpenMx", ref="stable")
Developers commit to the master
branch. Intrepid users are
encouraged to install the master
branch.
The stable
branch is updated automatically when all models/passing
and models/nightly
tests pass along with make cran-check
.
