[jira] [Updated] (SPARK-29577) Implement p-value simulation and
unit tests for chi2 test
[ https://issues.apache.org/jira/browse/SPARK-29577?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Dongjoon Hyun updated SPARK-29577:
----------------------------------
Target Version/s: (was: 2.4.5, 3.0.0)
> 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: 3.0.0
> Reporter: Alexander Tronchin-James
> Priority: Major
> Labels: ml, mllib
> Original Estimate: 168h
> Remaining Estimate: 168h
>
> 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.
