    I am using the Factor Analysis module.

    I already used the same model before on different data and worked fine. However, with the current data, when using “getEstimators” function, it gives me the following error:
    Exception in thread “AWT-EventQueue-0” java.lang.RuntimeException: failed to compute inverse

    I already calculated the factors and all for these data using SAS9.4 (to verify everything is in order).
