public override double LogProbabilityDensityFunction(
	Vector<double> x
)

Visual Basic

Public Overrides Function LogProbabilityDensityFunction ( 
	x As Vector(Of Double)
) As Double

C++/CLI

public:
virtual double LogProbabilityDensityFunction(
	Vector<double>^ x
) override

abstract LogProbabilityDensityFunction : 
        x : Vector<float> -> float 
override LogProbabilityDensityFunction : 
        x : Vector<float> -> float

Parameters

x Vector<Double>: A full point, or a point with its last coordinate omitted and inferred as one minus the supplied coordinates' sum.

Return Value

Double
The log density, negative infinity outside the open simplex, or NaN when an evaluated coordinate is NaN.

Remarks

Zero and unit coordinates use the outside-support convention; singular boundary limits are not evaluated. Full points must sum to one within the simplex tolerance.

Exceptions

ArgumentNullException	x is null.
DimensionMismatchException	The point has neither supported length.
