[jira] [Commented] (MADLIB-947) Support grouping for PCA

    [ https://issues.apache.org/jira/browse/MADLIB-947?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15765107#comment-15765107 ] 

Nandish Jayaram commented on MADLIB-947:
----------------------------------------

[~fmcquillan] The current behavior of PCA is to throw an error corresponding to the "_ignore any other columns that do not affect above logic_" case.
Is it alright to maintain the same behavior and error out instead of ignoring such columns?
