Power distance function. Encapsulates GetDistance() on a newly constructed Distance.PowerDistance object as a Distance.Function delegate.

Namespace:  CenterSpace.NMath.Stats
Assembly:  NMathStats (in NMathStats.dll) Version: 3.4.0.0

Syntax

C#
public static Distance..::.Function PowerFunction(
	double p,
	double r
)
Visual Basic (Declaration)
Public Shared Function PowerFunction ( _
	p As Double, _
	r As Double _
) As Distance..::.Function
Visual C++
public:
static Distance..::.Function^ PowerFunction(
	double p, 
	double r
)

Parameters

p
Type: System..::.Double

[Missing <param name="p"/> documentation for "M:CenterSpace.NMath.Stats.Distance.PowerFunction(System.Double,System.Double)"]

r
Type: System..::.Double

[Missing <param name="r"/> documentation for "M:CenterSpace.NMath.Stats.Distance.PowerFunction(System.Double,System.Double)"]

Remarks

The power distance is computed as:
CopyC#
distance( x, y ) = ( |xi - yi|^p )^1/r
 Missing values are allowed. Pairs of elements are excluded from the distance measure when their comparison returns NaN. If all pairs are excluded, NaN is returned for the distance measure.
