symSEM: Symbolic Computation for Structural Equation Models

A collection of functions for symbolic computation using 'Ryacas' package for structural equation models. This package includes functions to calculate model-implied covariance (and correlation) matrix and sampling covariance matrix of functions of variables using the first-order Taylor approximation.
