Subject [jira] [Commented] (MATH-839) In "RealDistribution" implementations, rename method "cumulativeProbability(double,double)" to "probability(double,double)"
Date Sat, 04 Aug 2012 19:28:02 GMT

    [ https://issues.apache.org/jira/browse/MATH-839?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13428665#comment-13428665
] 

Dennis Hendriks commented on MATH-839:
--------------------------------------

This change has been discussed on the dev list, see http://apache-commons.680414.n4.nabble.com/Math-Package-quot-o-a-c-m-distribution-quot-td4637374.html#none

Steps to take are:
(x) add new method (3.1) 
(/) deprecate old method (3.1) done in rev 1369381
(x) move impl to new method (3.1) 
(x) redirect old method to new method (3.1) 
(x) remove old method (4.0) 

That is, we can do all the work for 3.1, except remove the old/deprecated 'cumulativeProbability'
method.

> The method currently named "cumulativeProbability(double,double)" in fact provides the
_probability_ of the variable to be within the given interval. The name "probability" would
thus be more accurate (and shorter).
