For R Square calculation in performance I am using Squared Correlation. But the value of Squared Correlation for my various models just come 1 or 0. Please help.

Note: I am using Linear Regression performance operator.

    Also what Performance Operator are you using, and what kind of label do you have?  If you post your process that might help troubleshoot as well.
