Hi I have observed that kurtosis values coming from apache spark has a difference of 3.
The value coming from excel and in R as same values(11.333) but the
kurtosis value coming from spark1.6 differs by 3 (8.333).
Please let me know if I'm doing something wrong.
I'm executing via sqlcontext.sql("select kurtosis(columnname) from
tablename)

Thanks and Regards
Arun
