public int[,] GetIncidenceMatrix()

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.
