Return the sample standard deviation of the values, which corrects for bias in estimating the variance by dividing by N-1 instead of N.

Return the standard deviation of the values.
Return the variance of the values.
A class for tracking the statistics of a set of numbers (count, mean and variance) in a numerically robust way. Includes support for merging two StatVarianceCounters.
Taken from Spark's StatCounter implementation removing max and min.
