Stats

class Stats[A] extends AnyRef

A very simple class wrapping an Iterable and providing basic statistics like mean and variance.

There is an implicit conversion from a Seq[A] to a Stats[A] imported with com.github.marklister.collections. So you do not need to do anything to use this class. Simply use the mean, stdDev or variance methods on an appropriate sequence:

import com.github.marklister.collections.io._
import com.github.marklister.collections._
Welcome to Scala version 2.10.1 (OpenJDK Server VM, Java 1.7.0_21).
Type in expressions to have them evaluated.
Type :help for more information.

scala> Seq(1,2,3).mean
res0: Double = 2.0
