mxSE: mxSE - Compute standard errors in OpenMx

Description

This function allows you to obtain standard errors for arbitrary expressions, named entities, and algebras.

Usage

mxSE(x, model, ...)

Arguments

x

the parameter to get SEs on (reference or expression)

model

the mxModel to use.

...

further named arguments passed to mxEval

Value

SE value(s) returned as a matrix.

Details

x can be the name of an algebra, a bracket address, named entity or arbitrary expression. It is a frontend-only file that works much like mxEval.
