Syntax

public double[] GetStatistics()

Public Function GetStatistics As Double()

public:
array<double>^ GetStatistics()

member GetStatistics : unit -> float[]

Type: Double
A double array containing output statistics. The following table describes the statistics available:

index	Description
0	Sum of the degrees of freedom for the within-covariance matrices.
1	Chi-squared statistic.
2	The degrees of freedom in the chi-squared statistic.
3	Probability of a greater chi-squared, respectively, of a test of the homogeneity of the within-covariance matrices. (Not computed when the pooled only covariance matrix is computed).
4 thru (4+nGroups)	Log of the determinant of each group's covariance matrix (not computed when the pooled only covariance matrix is computed) and of the pooled covariance matrix.
Last (nGroups + 1) elements	Sum of the weights within each group.
Last element	Sum of the weights in all groups.

Exceptions

Exception	Condition
EmptyGroupException	is thrown when there are no observations in a group.
CovarianceSingularException	is thrown when the variance-covariance matrix is singular.
