Subject [jira] [Commented] (MATH-987) SimpleRegression needs to be map/reducable
Date Fri, 31 May 2013 14:43:20 GMT

    [ https://issues.apache.org/jira/browse/MATH-987?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13671527#comment-13671527

Ajo Fod commented on MATH-987:
------------------------------

This includes a method to add SimpleRegression object to an existing one. The test method
added asserts that all data updated when a single data point is added are also updated when
SimpleRegression objects are added for both the intercept case and the no-intercept case.

> For map/reduce to work with SimpleRegression, there should be a way to add together stats
from multiple SimpleRegression objects.
