Properties

	Name	Description
	Generator	Returns the random generator used by the distribution to generate the random values. (Inherited from ProbabilityDistribution)
	Location	Gets the location parameter of the distribution.
	Order	Gets the order of the distribution.

Methods

	Name	Description
	CDF	Gives the cumulative probability at x. (Overrides ProbabilityDistributionCDF(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)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object)
	NextDouble	Generates a random value distributed according to the distribution. (Overrides ProbabilityDistributionNextDouble)
	PDF	Gives the probability density at x. (Overrides ProbabilityDistributionPDF(Double))
	Quantile	Gives the pth quantile of the distribution. (Overrides ProbabilityDistributionQuantile(Double))
	SetOrder	Sets the order and location parameters for the distribution.
	ToString	Returns a string that represents the current object. (Inherited from Object)

Remarks


            
             Return Erlang distributed random deviates according to:
            
                                  a-1  -bx
                            b (bx)    e
              p   (x) dx = ---------------- dx   for x > 0
               a,b             Gamma(a)
            
                         =  0                    otherwise
            
             The Erlang distribution is a special case of the Gamma distribution
             with integer valued order a.
