VSS.parallel {psych}

R Documentation

Compare real and random VSS solutions

Description

Another useful test for the number of factors is when the eigen values of a random matrix are greater than the eigen values of a a real matrix. Here we show VSS solutions to random data. A better test is probably fa.parallel.

Usage

VSS.parallel(ncases, nvariables,scree=FALSE,rotate="none")

Arguments

ncases	Number of simulated cases
nvariables	number of simulated variables
scree	Show a scree plot for random data – see omega
rotate	rotate="none" or rotate="varimax"

Value

VSS like output to be plotted by VSS.plot
