Problem Note 59687: The HP Principal Components node gives incorrect scores and score code when the Eigenvalue Source property is set to Covariance
 |  |  |  |  |
In SAS® Enterprise Miner™, the HP Principal Components node creates score code. However, if you run the node with the Eigenvalue Source property set to Covariance, then the generated score-code is incorrect. The code should center the data without also scaling it. However, the code also scales the data.
The resulting principal-component scores in the exported data are incorrect.
If you score data using the generated score-code, then the scored results are also incorrect.
There are no errors or warnings to indicate a problem.
