MxComputeHessianQuality-class

mxComputeHessianQuality

names of matrices containing free variables

freeSet

Tests whether the Hessian is positive definite
(model$output$infoDefinite) and, if so, computes the condition
number (model$output$conditionNumber). See Luenberger & Ye (2008)
Second Order Test (p. 190) and Condition Number (p. 239).

Facilitates treatment of statistical model specifications
    as things that can be generated and manipulated programmatically.
    Structural equation models may be specified with reticular action model matrices or paths,
    linear structural relations matrices or paths, or
    directly in matrix algebra.
    Fit functions include full information maximum likelihood,
    maximum likelihood, and weighted least squares.
    Example models include confirmatory factor, multiple group, mixture
    distribution, categorical threshold, modern test theory, differential
    equations, state space, and many others.
