Return Value
A
g by
nVariables by
nVariablesdouble array containing the
covariances. Where,
g =
nGroups+1 if
pooled, group covariance computation is specified or
g=1 if pooled covariance computation is specified.
When pooled only covariance matrices are computed, the
within-group covariance matrices are not computed. The
pooled covariance matrix is always computed and is returned
as the
g-th covariance matrix.
If this method is invoked before classification, the
unscaled covariance matrix will be returned.
