public class JainBoundaryStatistic
extends BoundaryStatistic

JainBoundaryStatistic provides an implementation for for BoundaryStatistic with an alternative method (the P2 Algorithm) to StdBoundaryStatistic. Note that the percentage-parameter in the constructor must be between 0 and 1.

A more detailed description of the algorithms can be found in the student thesis of Luis Lopez (No 1535) or in LDB No 1507:
