java.lang.Object

de.lmu.ifi.dbs.elki.utilities.datastructures.histogram.AbstractStaticHistogram

de.lmu.ifi.dbs.elki.utilities.datastructures.histogram.AbstractObjStaticHistogram<MeanVariance>

de.lmu.ifi.dbs.elki.utilities.datastructures.histogram.MeanVarianceStaticHistogram

All Implemented Interfaces:

Histogram, ObjHistogram<MeanVariance>

public class MeanVarianceStaticHistogram
extends AbstractObjStaticHistogram<MeanVariance>

Histogram class storing MeanVaraince object. The histogram will start with "bin" bins, but it can grow dynamically to the left and right.

Constructor Detail

MeanVarianceStaticHistogram

public MeanVarianceStaticHistogram(int bins,
                           double min,
                           double max)

Constructor.

Parameters:

bins - Number of bins

min - Cover minimum

max - Cover maximum

Method Detail

put

public void put(double coord,
       double val)

Update the value of a bin with new data.

Parameters:

coord - Coordinate

val - Value

putData

public void putData(double coord,
           MeanVariance data)

Aggregate new data into the histogram. Note that the actual definition of "aggregate" depends on the application. While a static histogram will likely perform this immediately, a flexible histogram will cache a number of observations. Data is combined by using MeanVariance.put(Mean).

Parameters:

coord - Coordinate

data - Data

makeObject

protected MeanVariance makeObject()

Description copied from class: AbstractObjStaticHistogram

Class to make a new object for the data store.

Specified by:

makeObject in class AbstractObjStaticHistogram<MeanVariance>

Returns:

New instance.
