Gilles commented on MATH881:

Shall I also remove this method:
{code}
/**
* For a random variable {@code X} whose values are distributed according to
* this distribution, this method returns {@code P(X = x)}. In other words,
* this method represents the probability mass function (PMF) for the
* distribution.
*
* @param x Point at which the PMF is evaluated.
* @return the value of the probability mass function at point {@code x}.
*/
double probability(double[] x);
{code}
?
We already discussed that all the (currently implemented) {{RealDistribution}} classes return
zero. I guess that is is even less likely that an exotic {{MultivariateRealDistribution}}
will soon be implemented...
> Eliminate meaningless properties in multivariate distribution classes

> Key: MATH881
> URL: https://issues.apache.org/jira/browse/MATH881
> Project: Commons Math
> Issue Type: Bug
> Affects Versions: 3.0
> Reporter: Phil Steitz
> Fix For: 3.1, 4.0
>
>
> The MultivariateRealDistribution interface includes the following properties which make
no sense for multivariate distributions:
> getSupportLowerBound, getSupporUpperBound, isSupportLowerBoundInclusive, isSupportUpperBoundInclusive
> In addition, the following property makes sense, but is unlikely to be useful:
> isSuportConnected
> All of these properties should be deprecated in 3.1 and dropped in 4.0
