Phil Steitz updated MATH-332:
-----------------------------
Fix Version/s: 2.1
> Replacement of the HasDensity<P>-interface with a "double density(double
> x)"-method on the AbstractContinuousDistribution
> -------------------------------------------------------------------------------------------------------------------------
>
> Key: MATH-332
> URL: https://issues.apache.org/jira/browse/MATH-332
> Project: Commons Math
> Issue Type: Improvement
> Reporter: Mikkel Meyer Andersen
> Fix For: 2.1
>
> Attachments: patch-all
>
> Original Estimate: 3h
> Remaining Estimate: 3h
>
> Removed the HasDensity<P>-interface and replaced it with a "public double
> density(double x)"-method on the AbstractContinuousDistribution-class (it
> throws an exception as default if the classes don't override the method).
> Implemented density-functions for the F-distribution, t-distribution, Weibull
> distribution, and Cauchy distribution (the only continuous ones without a
> density implemented).
> A side-effect is that ChiSquaredDistributionImpl now uses an internal
> GammaDistributionImpl instead of a GammaDistribution. This is the only
> "major" change.
> This improvement replaces https://issues.apache.org/jira/browse/MATH-330
> (density implementation for the F-distribution) and
> https://issues.apache.org/jira/browse/MATH-331 (density implementation for
> the other three distributions).
