Compare real and random VSS solutions

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.

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
