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.

See Also

• findRecursiveSetto group variables regarding the position in mediation chain.

Examples

path <- matrix(0, 9, 9)
path[4, 1] <- path[7, 4] <- NA
path[5, 2] <- path[8, 5] <- NA
path[6, 3] <- path[9, 6] <- NA
path[5, 1] <- path[8, 4] <- NA
path[6, 2] <- path[9, 5] <- NA
