Hi Arun,

                You can do df.agg(max(,,), min(..)).

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
