    Hi,
    excuse me? Please give a little bit more details about your setting, otherwise I can only say that the squares are simply added, since you then will gain the sum of squares...

    Hello,

    I would like to make sure that SumOfSquares represent the inversion of the sum of the squares of the distances between all objects in the cluster and the centroid of the cluster.

    Thank you.

    Best regards.
