Sidharth Rajeev commented on SPARK-13508:
-----------------------------------------
Ok. I will close this issue and if the helper method is there it will be good,
rather doing the below code everytime:
String tmp2=summaries.variance().toString().replace("[", "").replace("]", "");
Double value2 =Double.parseDouble(tmp2);
double varianceValue = Math.round( value2 * 100.0 ) /
100.0;
double sdValue = Math.sqrt(varianceValue);
> For direct retrival of Standard Deviation for Anlaytics

> As part of easying up the analytical capabilities, I would like to add the
> standard deviation as such. As of now variance is directly available. Its
> square root will give the standard deviation. But as direct functionality it
> will save the time of the data analysts/scientists.
