Moments

case class Moments(m0: Long, m1: Double, m2: Double, m3: Double, m4: Double) extends Product with Serializable

A class to calculate the first five central moments over a sequence of Doubles. Given the first five central moments, we can then calculate metrics like skewness and kurtosis.

m{i} denotes the ith central moment.
