Subject [jira] [Commented] (MATH-699) inverseCumulativeDistribution fails with cumulative distribution having a plateau
Date Sat, 26 Nov 2011 05:19:40 GMT


Sébastien Brisard commented on MATH-699:

Great observation by Christian - we can switch on plateau detection iff isSupportConnected
is false. Otherwise, I would say the "new" implementation is good to go.
Yes, it is indeed a very neat way to proceed. I'll make the changes once Christian's patch
for MATH-703 is committed.

I would also be happy to celebrate dropping all of the getXxx(p) methods, which are not needed
any more.
Good! So I do not need to post on the mailing list on this issue?

We can all thank Mikkel, btw, for suggesting a while back that we add the numerical mean,
variance and connected support properties. Came in very handy here!
I would also thank the guy who suggested Chebyshev's inequality (I wonder who that is ;)).
Overall, I personnally enjoyed working on this issue, as it truly was team work.

> 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.
