Christian Winter commented on MATH-699:
---------------------------------------
A different idea for solving the bracketing issue: We could solve the inverse cdf calculation
by transforming the domain [-∞;+∞] to [-1;+1] with arctan. More precisely,
we could do the first iterations of the solving step on the transformed domain, and we can
go back to original domain as soon as +/-1 aren't interval limits any more.
> inverseCumulativeDistribution fails with cumulative distribution having a plateau

> Key: MATH-699
> URL: https://issues.apache.org/jira/browse/MATH-699
> Project: Commons Math
> Issue Type: Bug
> Affects Versions: 3.0
> Reporter: Sébastien Brisard
> Assignee: Sébastien Brisard
> Priority: Minor
> Attachments: AbstractContinuousDistributionTest.java

> This bug report follows MATH-692. The attached unit test fails. As required by the definition
in MATH-692, the lower-bound of the interval on which the cdf is constant should be returned.
This is not so at the moment.
