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")
Number of simulated cases
number of simulated variables
Show a scree plot for random data -- see omega
rotate="none" or rotate="varimax"
VSS like output to be plotted by VSS.plot
Very Simple Structure (VSS)
# NOT RUN {
#VSS.plot(VSS.parallel(200,24))
# }
