Subject [jira] Updated: (MATH-506) The static field ChiSquareTestImpl.distribution serves no purpose
Date Sat, 05 Feb 2011 03:17:30 GMT

     [ https://issues.apache.org/jira/browse/MATH-506?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Phil Steitz updated MATH-506:
-----------------------------

    Affects Version/s:     (was: 2.1)

See the discussion in MATH-349 where it was decided to remove the distribution pluggability
in 3.0.  In 2.x, the distribution is pluggable and the instance field is useful.  The 3.0
code in trunk removes the pluggability and makes the field useless.

> The static field ChiSquareTestImpl.distribution serves no purpose.
> There is a setter for it, but in every case where the field is used, it is first overwritten
with a new value.
> The field and the setter should be removed, and the methods that create a new instance
should create a local variable instead.
> For Math 2.1, the field can be removed and the setter deprecated.
