Returns the power distance between two data sets, using the current values of parameters p and r.

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

Syntax

C#
public double GetDistance(
	DoubleVector data1,
	DoubleVector data2
)
Visual Basic (Declaration)
Public Function GetDistance ( _
	data1 As DoubleVector, _
	data2 As DoubleVector _
) As Double
Visual C++
public:
double GetDistance(
	DoubleVector^ data1, 
	DoubleVector^ data2
)

Parameters

data1
Type: CenterSpace.NMath.Core..::.DoubleVector
The first data set.
data2
Type: CenterSpace.NMath.Core..::.DoubleVector
The second data set.

Return Value

The power distance between data1 and data2.

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.

Exceptions

ExceptionCondition
CenterSpace.NMath.Core..::.MismatchedSizeException Thrown if the given data sets do not have equal lengths.
