R: Compare real and random VSS solutions

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
