path_to_network: Precision matrix from ordered path model

In SEset: Computing Statistically-Equivalent Path Models

Precision matrix from ordered path model

Description

Takes a path model and generates the corresponding (standardized) precision matrix or covariance matrix. The inverse of network_to_path.

Usage

path_to_network(B, psi = NULL, output = "precision")

Arguments

B	input p \times p weights matrix
psi	variance-covariance matrix for the residuals. If NULL (the default) will impose the constraint that the variables have variance 1 and the residuals are uncorrelated
output	Function returns the precision ("precision") or covariance ("covariance") matrix

Value

a p \times p precision or covariance matrix
