"PCA SEVERE: java.lang.ArrayIndexOutOfBoundsException"

Hi,

I am using rapid miner to try and predict several numeric labels based on numeric attributes.
The dataset has a high deminsionality with many attributes
The attributes are highly correalated so im using a PCA operator to create uncorrealated components. The result of which are fed into a Regression operator to see if it is more effective than using just the regression operator on its own

The issue arises when i change the label. For the example below, the PCA operator works perfectly well when setting the role of Attr1 to label
However when i change the label to Attr2 i get an error SEVERE: java.lang.ArrayIndexOutOfBoundsException

Role Name Type Stats                        Range                 Missing Values
regular Attr1 real         avg = 69.584 +/- 20.640 [0.000 ; 100.000] 0.0
regular Attr2 real         avg = 63.434 +/- 18.475 [0.000 ; 97.143] 0.0

Im new to rapidminer so any help would be greatly appreciated

Thanks

    Hi,

    can you please post your process setup as described here? If your data is not confidential, it would also be helpful if you could create a bug at http://bugs.rapid-i.com and attach the data (beware, the data will be publicly downloadable from the internet). If the data is too confidential for the internet but public enough for a mail, you could mail me the data for investigation. In that case I can send you my mail address via forum PM.

    Best, Marius
