[jira] [Updated] (MATH-1409) "UncorrelatedRandomVectorGenerator" is shaky

     [ https://issues.apache.org/jira/browse/MATH-1409?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Gilles updated MATH-1409:
-------------------------
    Description: 
This unit test (package "o.a.c.m.random") is too sensitive to the seed.
Using a fixed seed to make it pass (rather than relaxing the tolerance) gives a wrong impression about the code's purpose (or potentially hides a bug).
