[jira] [Created] (SPARK-29577) Implement p-value simulation and unit tests for chi2 test

Alexander Tronchin-James created SPARK-29577:
------------------------------------------------

             Summary: Implement p-value simulation and unit tests for chi2 test
                 Key: SPARK-29577
                 URL: https://issues.apache.org/jira/browse/SPARK-29577
             Project: Spark
          Issue Type: Improvement
          Components: ML, MLlib
    Affects Versions: 2.4.5, 3.0.0
            Reporter: Alexander Tronchin-James


Spark mllib's chi-squared test does not yet include p-value simulation for the goodness of fit test, and implementing a robust/scaleable approach was non-trivial for us, so we wanted to give this work back to the community for others to use.
