[jira] [Commented] (MAHOUT-1962) Add F-test to Linear Regression
Fitness Tests
[ https://issues.apache.org/jira/browse/MAHOUT-1962?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15955194#comment-15955194 ]
Dustin VanStee commented on MAHOUT-1962:
----------------------------------------
I created a pull request for this Jira
Here are a few other mods
-- added 2 tests for OLS
-- modified print statement for summary
-- changed degreeOfFreedom to X.ncols - 1 to remove intercept
-- proposing to move intercept to first column .... (no change here, just a comment ...)
This is first pull request, so let me know if there are some processes I missed.
Also, how can I assign myself this JIRA ?
