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
