Thomas Neidhart commented on MATH-1065:
---------------------------------------
Thanks for the better explanation of the problem.
I am still searching for a mathematical definition of such a distribution as I
mainly looked at the referenced wikipedia page and derived the above algorithm
from the cdf graph that is available there, although I am of course unsure if
it is correct.
> EnumeratedRealDistribution.inverseCumulativeProbability returns values not in
> the samples set
