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

Description

Find the appropriate position for freely estimated correlation (or covariance) given a regression coefficient matrix. The appropriate position is the pair of variables that are not causally related.

Usage

findPossibleFactorCor(beta)

Arguments

beta

The regression coefficient in path analysis.

Value

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