Subject: Need to user univariate summary stats
Hi
I'm currently using query
sqlContext.sql("SELECT MAX(variablesArray) FROM " + tableName)
to extract mean max min.
is there any better optimized way ?
In the example i saw df.groupBy("key").agg(skewness("a"), kurtosis("a"))
But i don't have key anywhere in the data.
How to extract the univariate summary stats from df. please help

Thanks and Regards
Arun
