Hi,
Does anybody know what could be a good reason(s) that Factor analysis
results from Splus6 and version 9 of SAS are a little different?
Scores of Factors 1 and 2 are similar in both analysis, but they change
starting at factor3 and 4.
Here is a sample from the data run in Splus and SAS:
In Splus6 in Linux OS server I applied factanal function with method=mle.
The output of the scores follow with symbols Factor1mle etc.
In SAS version 9 for windows I applied the procedure:
proc factor method=ml score
The output of the scores follow with symbols Factor1 etc.
In both cases I kept 4 factors.
Obs Factor1mle Factor2mle Factor3mle
Factor4mle Factor1 Factor2 Factor3 Factor4
