Class ApplyRandomArrivalTimeShift

java.lang.Object

fact.utils.ApplyRandomArrivalTimeShift

All Implemented Interfaces:

stream.Processor

public class ApplyRandomArrivalTimeShift
extends Object
implements stream.Processor

add random offsets to an array of arrival times. The offset is sampled from a gaussian distribution around zero with a given standard deviation. The standard deviation is determined from a mean standard deviation stdDevOrigin of the original (arrival time) distribution and a variance stdDevGoal, which is the mean standard deviation of the desired (arrival time) distribution.
