BetaDistribution Constructor

Initializes a new β distribution.

Namespace:  Meta.Numerics.Statistics.Distributions
Assembly:  Meta.Numerics (in Meta.Numerics.dll) Version: 4.0.5.0 (4.0.5.0)
Syntax
public BetaDistribution(
	double alpha,
	double beta
)

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
ExceptionCondition
ArgumentOutOfRangeExceptionalpha 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.
