That shouldn't be a surprise: an r2_score of 0 is chance. What you are finding is that you can produce result that go below chance. Negative r2_scores are common. Sometimes, I am even happy when my r2_score finally goes above zero. G ------------------------------------------------------------------------------ Everyone hates slow websites. So do we.
