de.uka.ipd.sdq.simucomframework.stopcondition.ConfidenceStopCondition

All Implemented Interfaces:

de.uka.ipd.sdq.simulation.abstractsimengine.SimCondition, org.palladiosimulator.measurementframework.listener.IMeasurementSourceListener

public class ConfidenceStopCondition
extends Object
implements de.uka.ipd.sdq.simulation.abstractsimengine.SimCondition, org.palladiosimulator.measurementframework.listener.IMeasurementSourceListener

Provides a stop condition which determines when to stop based on the confidence interval around a point estimation (e.g. mean).
