Andrew Waterman commented on MATH-460:
--------------------------------------
I've taken another stab at most of the class, doing an independent
implementation working from the equations presented in Wikipedia and modifying
the implementation where it differed from Pavel's. I haven't been able to
implement the following, the JavaDoc is a bit vague in RealDistribution:
/**
* Use this method to get information about whether the lower bound
* of the support is inclusive or not.
*
* @return whether the lower bound of the support is inclusive or not
*/
boolean isSupportLowerBoundInclusive();
/**
* Use this method to get information about whether the upper bound
* of the support is inclusive or not.
*
* @return whether the upper bound of the support is inclusive or not
*/
isSupportUpperBoundInclusive();
/**
* Use this method to get information about whether the support is
connected,
* i.e. whether all values between the lower and upper bound of the support
* are included in the support.
*
* @return whether the support is connected or not
*/
boolean isSupportConnected();
Love some clarification (links would be appreciated) and I can try and continue
on a bit further. Otherwise, I have some work that I can attach to share with
the future. :)
