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

Description

The correct_alpha function accomplishes Step 4 of the algorithm with regard to replications of the estimated intercept or mean vector. More specifically, the correct_alpha function re-orders and/or re-signs as needed within the estimated intercept or mean vector for each replication so that all replications uniformly follow the order and sign pattern defined by the population values.

Usage

correct_alpha(P_data, rep, n.eta, sample_alpha)

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_alpha	a list containing replications of the estimated intercept or mean vector.

Details

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