case class Stats(count: Long, mean: Double, varnum: Double, min: Double, max: Double) extends Product with Serializable

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 Stats objects. Based on Welford and Chan's algorithms for running variance.
