public class COptQuestExponentialRandomVariable
extends COptQuestUserControlledVariable

A random variable with an exponential distribution: the time between events that occur at random at a constant average rate. scale, which must be greater than 0, is the mean time. The rate is 1 / scale.

The engine draws a new value at the start of every replication. The probability distribution is COptQuestExponentialDistribution.

public COptQuestExponentialRandomVariable(String name,
 double scale)
                                   throws COptQuestException

Constructs a new exponential random variable with the specified name and scale parameter.

Parameters:

name - the name/identifier of this random variable (used for reporting, logging, or display purposes)

scale - the scale parameter of the exponential distribution (mean = scale, rate = 1/scale) must be positive (> 0)

Throws:

COptQuestException
