Classify a set of observations using the linear or quadratic discriminant functions generated during the training process.

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

Syntax

public void Classify(
	double[,] x
)

Public Sub Classify ( 
	x As Double(,)
)

public:
void Classify(
	array<double,2>^ x
)

member Classify : 
        x : float[,] -> unit

x: Type: SystemDouble
A double matrix containing the observations with at least nVariables columns. The first nVariables columns correspond to the variables. Reclassification does not require group numbers be present. Any additional columns will be ignored.

Exceptions

Exception	Condition
SumOfWeightsNegException	is thrown when the sum of the weights have become negative.
EmptyGroupException	is thrown when there are no observations in a group.
CovarianceSingularException	is thrown when the variance-covariance matrix is singular.

Remarks

An InvalidOperationException is thrown if the leave-out-one classification method is chosen.
