SymMatrix-class: Symmetric matrix object: Random parameters symmetric matrix

Description

This object can be used to represent a symmetric matrix in SEM model. It contains free parameters, fixed values, and starting values. This object can be represented factor correlation or error correlation matrix.

Objects from the Class

This object is created by "symMatrix" function. Objects can be also created by calls of the form new("SymMatrix", ...).

Extends

Class "SimMatrix", directly.
