All Implemented Interfaces:

ProbabilityCalculator

public class CompoundCalculator

extends Object

implements ProbabilityCalculator

Calculates the combined probability using the standard compound probability algorithm.

Specifically:

	ab...n / ab...n + (1-a)(1-b)...(1-n)
 

Where: 'a' and 'b' are discrete probabilities
