Class FrequencyBucketDistribution

java.lang.Object

net.objectlab.kit.util.FrequencyBucketDistribution

public class FrequencyBucketDistribution
extends Object

Very basic distribution count per bucket. It is not meant to handle extreme large dataset and the calculation is quite basic and inefficient at the moment. Given a list of bucket upper limits, the distribution will count the number of occurrences. If a value is <= bucket (ordered) then the count is incremented. If the value is > than the upper limit then the count is incremented for an upper limit bucket.
