Github user cooper-sloan commented on the issue: https://github.com/apache/incubator-madlib/pull/149 In regards to 'nan' issue. We have run across this in the past. It has to do with regularization, which is scheduled for phase 2. Once we implement regularization this issue should go away. However I will try recreate this bug and verify that is the true issue.
