One of the types of objects in Praat.
An object of type Covariance represents the sums of squares and cross products of a multivariate data set divided by the number of observations.
An object of type Covariance contains the same attributes as an object of type SSCP.
Since an object of type Covariance contains the mean values (the centroids), the covariances as well as the number of observations it has all the information necessary to be the subject of all kinds of statistical tests on means and variances.
