findPossibleFactorCor {simsem}

Find the appropriate position for freely estimated correlation (or covariance) given a regression coefficient matrix

Description

Usage

findPossibleFactorCor(beta)

Arguments

beta

The regression coefficient in path analysis.

Value

The symmetric matrix containing the appropriate position for freely estimated correlation.
