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

Description

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

Usage

correct_gamma(P_data, rep, n.eta, sample_gamma)

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_gamma	a list containing replications of the estimated eta on eta regression coefficient matrix.

Details

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