WebThus, saying "SSbetween for centroids (as points) is maximized" is alias to say "the (weighted) set of squared distances between the centroids is maximized". Note: in SSbetween each centroid is weighted by the number of points Ni in that cluster i. That is, each centroid is counted Ni times. For example, with two centroids in the data, 1 and 2 ...
