Class H1DA

java.lang.Object

com.flaptor.hist4j.AdaptiveHistogram

jhplot.H1DA

All Implemented Interfaces:

Serializable

public class H1DAextends AdaptiveHistogram

Adaptive histogram in one dimension (1D). This class implements a histogram that adapts to an unknown data distribution. It keeps a more or less constant resolution throughout the data range by increasing the resolution where the data is more dense. For example, if the data has such such a distribution that most of the values lie in the 0-5 range and only a few are in the 5-10 range, the histogram would adapt and assign more counting buckets to the 0-5 range and less to the 5-10 range. This implementation provides a method to obtain the accumulative density function for a given data point, and a method to obtain the data point that splits the data set at a given percentile.
