Sriram Natarajan created MATH-1185:
--------------------------------------
Summary: Tail probability drops to zero beyond 10e-17 ?
Key: MATH-1185
URL: https://issues.apache.org/jira/browse/MATH-1185
Project: Commons Math
Issue Type: Wish
Affects Versions: 3.3, 3.4
Reporter: Sriram Natarajan
Priority: Minor
This could be a simple question, In which case I can expect a clarification.
If this is the wrong place to post such a question, let me know.
OS: Windows 8.1, Java 1.8.0_25
ChiSquaredDistribution chisq = new ChiSquaredDistribution(23)
1.0 - chisq.cumulativeProbability(130) is 1.1102230246251565E-16
1.0 - chisq.cumulativeProbability(131) is 0.0
Am pretty sure it is not a formatting issue. Is there a reason why the tail
drops to zero at this point?
