Beta Method (trueCount, falseCount)

Microsoft Research, Cambridge

Creates a beta distributed random variable from initial counts.

Declaration Syntax

Visual Basic

Visual C++

public static Variable<double> Beta(
	double trueCount,
	double falseCount
)

Public Shared Function Beta ( _
	trueCount As Double, _
	falseCount As Double _
) As Variable(Of Double)

public:
static Variable<double>^ Beta(
	double trueCount, 
	double falseCount
)

Parameters

trueCount (Double): The initial count of successes.

falseCount (Double): The initial count of failures.

Return Value

x ~ Beta(trueCount,falseCount)

Remarks

The formula for the distribution is p(x) = (Gamma(trueCount+falseCount)/Gamma(trueCount)/Gamma(falseCount)) x^{trueCount-1} (1-x)^(falseCount-1) where x lies between 0 and 1.
