WebWe use a little trick: we square the errors and find a line that minimizes this sum of the squared errors. ∑ et2 = ∑(Y i − ¯¯¯ ¯Y i)2 ∑ e t 2 = ∑ ( Y i − Y ¯ i) 2. This method, the method of least squares, finds values of the intercept and slope coefficient that minimize the sum of the squared errors. To illustrate the concept ... WebInterpretation. The within-cluster sum of squares is a measure of the variability of the observations within each cluster. In general, a cluster that has a small sum of squares is more compact than a cluster that has a large sum of squares. Clusters that have higher values exhibit greater variability of the observations within the cluster.
