Constructor Details

GammaDistributionFromMoments

public GammaDistributionFromMoments(double mean,
 double coefficientOfVariance,
 IRandomGenerator rng)

Constructs a GammaDist object based on the distribution mean and distribution coefficient of variance.

Parameters:

distribution - mean

coefficient - of variance ( = standard deviation / mean)
