DiscriminantAnalysis.Update Method (Double[,])

Processes a set of observations and performs a linear or quadratic discriminant function analysis among the several known groups.

public void Update(
double[,] x
);

Parameters

x: A double matrix containing the observations.

Remarks

The first nVariables columns correspond to the variables, and the last column (column nVariables) contains the group numbers. The groups must be numbered 1,2, ..., nGroups.

Exceptions

Exception Type	Condition
SumOfWeightsNegException	is thrown if the sum of the weights have become negative.
EmptyGroupException	is thrown if there are no observations in a group. Cannot compute statistics.
CovarianceSingularException	is thrown if the variance-Covariance matrix is singular.
PooledCovarianceSingularException	is thrown if the pooled variance-Covariance matrix is singular.
