public class ExponentialDistribution : ContinuousDistribution

The ExponentialDistribution type exposes the following members.

Constructors

	Name	Description
	ExponentialDistribution	Initializes a new instance of the ExponentialDistribution class, using a StandardGenerator as underlying random number generator.
	ExponentialDistribution(Double)	Initializes a new instance of the ExponentialDistribution class, using the default random number generator.
	ExponentialDistribution(Generator)	Initializes a new instance of the ExponentialDistribution class, using the specified Generator as underlying random number generator.
	ExponentialDistribution(Double, Generator)	Initializes a new instance of the ExponentialDistribution class, using the specified Generator as underlying random number generator.

Properties

	Name	Description
	CanReset	Gets a value indicating whether the random number distribution can be reset, so that it produces the same random number sequence again. (Inherited from Distribution)
	Generator	Gets or sets a Generator object that can be used as underlying random number generator. (Inherited from Distribution)
	Lambda	Gets or sets the parameter lambda which is used for generation of exponential distributed random numbers.
	Maximum	Gets the maximum possible value of exponential distributed random numbers. (Overrides DistributionMaximum)
	Mean	Gets the mean value of exponential distributed random numbers. (Overrides DistributionMean)
	Median	Gets the median of exponential distributed random numbers. (Overrides DistributionMedian)
	Minimum	Gets the minimum possible value of exponential distributed random numbers. (Overrides DistributionMinimum)
	Mode	Gets the mode of exponential distributed random numbers. (Overrides DistributionMode)
	Variance	Gets the variance of exponential distributed random numbers. (Overrides DistributionVariance)

Methods

	Name	Description
	CDF(Double)	(Overrides ContinuousDistributionCDF(Double))
	CDF(Double, Double)
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object)
	GetHashCode	Serves as the default hash function. (Inherited from Object)
	GetType	Gets the Type of the current instance. (Inherited from Object)
	Initialize	Updates the helper variables that store intermediate results for generation of exponential distributed random numbers.
	IsValidLambda	Determines whether the specified value is valid for parameter Lambda.
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object)
	NextDouble	Returns a exponential distributed floating point random number. (Overrides DistributionNextDouble)
	PDF(Double)	(Overrides ContinuousDistributionPDF(Double))
	PDF(Double, Double)
	Quantile(Double)	(Overrides ContinuousDistributionQuantile(Double))
	Quantile(Double, Double)
	Reset	Resets the random number distribution, so that it produces the same random number sequence again. (Inherited from Distribution)
	ToString	Returns a string that represents the current object. (Inherited from Object)

Fields

	Name	Description

Remarks

The implementation of the ExponentialDistribution type bases upon information presented on Wikipedia - Exponential distribution.

Copy

Return exponentially distributed random deviates according to:

p (x) = lambda * exp(-lambda x) dx   for x >= 0
 l
      = 0                    otherwise

The probability density has mean = stdev = 1/lambda.
