public class COptQuestNormalRandomVariable
extends COptQuestUserControlledVariable

A random variable with a normal distribution. The values spread symmetrically around mean. sigma, which must be greater than 0, is the standard deviation. About 95 percent of the values are within 2 * sigma of mean.

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

public COptQuestNormalRandomVariable(String name,
 double mean,
 double sigma)
                              throws COptQuestException

Constructs a new normal random variable with the specified name, mean, and standard deviation.

Parameters:

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

mean - the mean (location parameter, μ) of the normal distribution

sigma - the standard deviation (scale parameter, σ > 0) of the normal distribution

Throws:

COptQuestException
