In REREFACT: Reordering and/or Reflecting Factors for Simulation Studies with Exploratory Factor Analysis

Description

The correct_psi function accomplishes Step 4 of the algorithm with regard to replications of the estimated covariance matrix for the vector of residuals for eta. More specifically, the correct_psi function re-orders and/or re-signs as needed within the estimated covariance matrix for the vector of residuals for eta for each replication of a simulation study with exploratory factor analysis.

Usage

correct_psi(P_data, rep, n.eta, sample_psi)

Arguments

P_data	a list containing the correct permutation matrix, P_i, for each replication.
rep	the number of replications.
n.eta	the total number of latent variables within eta.
sample_psi	a list containing replications of the estimated covariance matrix for the vector of residuals for eta.

Details

The correct_psi function uses P to re-order and/or re-sign as needed within the estimated covariance matrix for the vector of residuals for eta for each replication of a simulation study with exploratory factor analysis. This function returns a list, correct_psi, of the re-ordered and/or re-signed estimated covariance matrix for the vector of residuals for eta for each replication and saves the list as a text file to the designated working directory.
