Thomas Neidhart updated MATH-968:
---------------------------------
Attachment: MATH-968.zip
Please find attached a patch that add support for the Pareto distribution.
The test values have been created with R (cran modules VGAM contains a pareto
distribution), although there seems to be a small bug in the module as the
density for x == scale/k is returned as 0.
Looking at the wikipedia page or wolfram
(http://reference.wolfram.com/mathematica/ref/ParetoDistribution.html) you can
see that for this case the density should be <> 0. So I adapted the test values
for this case.

> Seems that org.apache.commons.math3.distribution lacks a ParetoDistribution

> would be very nice!
