Covariances.GetIncidenceMatrix Method

CovariancesGetIncidenceMatrix Method

Returns the incidence matrix. Note that the Compute method must be invoked first before invoking this method. Otherwise, the method throws a NullReferenceException exception.

Namespace: Imsl.Stat
Assembly: ImslCS (in ImslCS.dll) Version: 6.5.2.0

Syntax

C++

Copy

public int[,] GetIncidenceMatrix()

Public Function GetIncidenceMatrix As Integer(,)

public:
array<int,2>^ GetIncidenceMatrix()

member GetIncidenceMatrix : unit -> int[,]

Return Value

Type: Int32
An int matrix containing the incidence matrix.

Remarks

If MissingValueMethod is 0, incidence matrix is 1 x 1 and contains the number of valid observations; otherwise, incidence matrix is x.GetLength(1) x x.GetLength(1) and contains the number of pairs of valid observations used in calculating the crossproducts for covariance.
