Subject [jira] [Created] (MATH-1181) KolmogorovSmirnov test algorithm choice prone to integer overflow
Date Mon, 15 Dec 2014 13:10:13 GMT
Phil Steitz created MATH-1181:
---------------------------------

             Summary: KolmogorovSmirnov test algorithm choice prone to integer overflow
                 Key: MATH-1181
                 URL: https://issues.apache.org/jira/browse/MATH-1181
             Project: Commons Math
          Issue Type: Bug
    Affects Versions: 3.3
            Reporter: Phil Steitz
             Fix For: 3.4


The computation used to select the algorithm in the 2-sample KS test is prone to integer overflow,
resulting in the "exact" method being chosen for very large samples, resulting in impractically
long execution time.
