Interface PSquarePercentile.PSquareMarkers

Enclosing class:

PSquarePercentile

protected static interface PSquarePercentile.PSquareMarkers

An interface that encapsulates abstractions of the P-square algorithm markers as is explained in the original works. This interface is exposed with protected access to help in testability.

Method Summary

Modifier and Type	Method and Description
PSquarePercentile.PSquareMarkers	copySelf() A deep copy function to clone the current instance.
double	estimate(int index) An Estimate of the percentile value of a given Marker
double	getPercentileValue() Returns Percentile value computed thus far.
double	height(int markerIndex) Returns the marker height (or percentile) of a given marker index.
double	processDataPoint(double inputDataPoint) Process a data point by moving the marker heights based on estimator.

Method Detail

getPercentileValue

double getPercentileValue()

Returns Percentile value computed thus far.

Returns:

percentile

copySelf

PSquarePercentile.PSquareMarkers copySelf()

A deep copy function to clone the current instance.

Returns:

deep copy of this instance

height

double height(int markerIndex)

Returns the marker height (or percentile) of a given marker index.

Parameters:

markerIndex - is the index of marker in the marker array

Returns:

percentile value of the marker index passed

Throws:

MathIllegalArgumentException - in case the index is not within [1-5]

processDataPoint

double processDataPoint(double inputDataPoint)

Process a data point by moving the marker heights based on estimator.

Parameters:

inputDataPoint - is the data point passed

Returns:

computed percentile

estimate

double estimate(int index)

An Estimate of the percentile value of a given Marker

Parameters:

index - the marker's index in the array of markers

Returns:

percentile estimate

Throws:

MathIllegalArgumentException - in case if index is not within [1-5]
