\title{Numerically estimate the Jacobian with respect to free parameters}
\usage{
mxComputeJacobian(freeSet=NA_character_, ..., of = "expectation",
defvar.row=as.integer(NA), data='data')
}
\arguments{
\item{freeSet}{names of matrices containing free variables}
\item{...}{Not used. Forces remaining arguments to be specified by name.}
\item{of}{a character vector of expectations or algebra names}
\item{defvar.row}{A row index. Which row to load for definition variables.}
\item{data}{From which data to load definition variables.}
}
\description{
When algebra names are given, all algebras must belong to the same
model.
When expectations are given, the Jacobian is taken with respect
to the manifest model.
The manifest model excludes any latent variables or processes. For
RAM and LISREL models, the manifest model contains only the
manifest variables with free means, covariance, and thresholds.
Ordinal manifest variables are standardized.
