> 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
