Subject svn commit: r1167600 - /commons/proper/math/trunk/src/site/xdoc/changes.xml
Date Sat, 10 Sep 2011 20:21:52 GMT
Author: gregs
Date: Sat Sep 10 20:21:52 2011
New Revision: 1167600

URL: http://svn.apache.org/viewvc?rev=1167600&view=rev
Log:
(MATH-649) SimpleRegression needs the ability to suppress the intercept 						

This commit pushes changes to allow the estimation of the a regression in which the intercept
is constrained to be zero. I am also pushing changes to change.xml.
