Namespace: Numerics.NET.DataAnalysis
Assembly: Numerics.NET (in Numerics.NET.dll) Version: 10.8.0

WeightedMean<C>(ColumnSelector, ColumnSelector)	Creates a descriptor that computes weighted means for selected value/weight column pairs.
WeightedMean<C>(C, C)	Creates a descriptor that computes the weighted mean of one column using another as weights.

Creates a descriptor that computes weighted means for selected value/weight column pairs.

)

Visual Basic

Public Shared Function WeightedMean(Of C) ( 
	values As ColumnSelector,
	weights As ColumnSelector
) As Aggregation(Of C, String)

C++/CLI

public:

Aggregation<C, String>
A weighted-mean aggregation descriptor.

Selector-based binary descriptors expand cartesian.
