[jira] [Created] (HIVE-9229) How to calculate the Kendall
coefficient of correlation?
Marcin Kosiński created HIVE-9229:
-------------------------------------
Summary: How to calculate the Kendall coefficient of correlation?
Key: HIVE-9229
URL: https://issues.apache.org/jira/browse/HIVE-9229
Project: Hive
Issue Type: Wish
Reporter: Marcin Kosiński
Priority: Trivial
In this [wiki page](https://cwiki.apache.org/confluence/display/Hive/LanguageManual+UDF) there is a function `corr()` that calculates the Pearson coefficient of correlation, but my question is that: is there any function in Hive that enables to calculate the Kendall coefficient of correlation of a pair of a numeric columns?
In anyone has any idea on how to even implement it please answer on [this](http://stackoverflow.com/questions/27231039/hive-how-to-calculate-the-kendall-coefficient-of-correlation) stackoverflow question.
Thanks for help,
Marcin
