Package likelihoodDetectionModule.normalizer

Class DecayingAverageNorm

java.lang.Object

likelihoodDetectionModule.normalizer.DecayingAverageNorm

All Implemented Interfaces:

Normalizer

public class DecayingAverageNorm
extends Object
implements Normalizer

This class implements the decaying average normalizer/estimator for the likelihoodDetectionModule. The signal is estimated using a simple ExponentialAverager, and the background is estimated using a TwoSpeedExponentialAverager.

DecayingAverageNorm

public DecayingAverageNorm(List<DecayingAverageNormAlphas> alphas,
 double referenceGain)

Constructor

Parameters:

alphas - A list of DecayingAverageNormAlphas describing each signal/background pair for each band (be it a signal or guard band).

referenceGain - The referenceGain is used to scale the signal estimate before passing it to the TwoSpeedExponentialAverager. See it's JavaDoc for a description of how this is used in it's calculation.
