BetaDistribution Constructor

Initializes a new β distribution.

Namespace: Meta.Numerics.Statistics.Distributions
Assembly: Meta.Numerics (in Meta.Numerics.dll) Version: 4.1.4

Syntax

public BetaDistribution(
	double alpha,
	double beta
)

Public Sub New ( 
	alpha As Double,
	beta As Double
)

public:
BetaDistribution(
	double alpha, 
	double beta
)

new : 
        alpha : float * 
        beta : float -> BetaDistribution

Parameters

alpha: Type: SystemDouble
The left shape parameter, which controls the form of the distribution near x=0.
beta: Type: SystemDouble
The right shape parameter, which controls the form of the distribution near x=1.

Exceptions

Exception	Condition
ArgumentOutOfRangeException	alpha or beta is non-positive.

Remarks

The alpha shape parameter controls the form of the distribution near x=0. The beta shape parameter controls the form of the distribution near z=1. If a shape parameter is less than one, the PDF diverges on the side of the distribution it controls. If a shape parameter is greater than one, the PDF goes to zero on the side of the distribution it controls. If the left and right shape parameters are equal, the distribution is symmetric about x=1/2.
