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.
stable branch can be considered our
current alpha release.
An easy way to install the
stable branch is
require(devtools) install_github("OpenMx/OpenMx", ref="stable")
Developers commit to the
master branch. Intrepid users are
encouraged to install the
stable branch is updated automatically when all
models/nightly tests pass along with
