[ https://issues.apache.org/jira/browse/MATH-437?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Luc Maisonobe updated MATH-437: --- Attachment: ks-distribution.patch Would the ks-distribution.patch patch be an acceptable way to implement the real distribution interface and solve the issue? Note that the implementations is really basic numerical computation using the cumulative probability as the reference. There are surely much better ways to do that. In particular, there seems to be exact formulas to compute the first moments (see the comments in the code and in the test case). I did not set up the test case to implement the abstract test shared by all distributions, but it would need to be done too. If the patch is not acceptable, could we push this issue to 4.0?

Now the results are consistent with those of R and implementation by Simard and L'Ecuyer. The implementation can be made faster, but then n approx. larger than 140 cannot be dealt with.
