WebThe sum of squares for the first n integers = (n) (n+1) (2n+1)/6 - this is a pretty well known summation. To get the sum of squares of the first n EVEN integers, we just need to adjust that formula a little bit: plug in n/2 instead of n (so in this case 500 instead of 1000) and multiply the result by four. WebThe Squared Euclidean distance (SED) is defined as the sum of squares of the differences between coordinates.

WebHere are some basic characteristics of the measure: Since r 2 is a proportion, it is always a number between 0 and 1.; If r 2 = 1, all of the data points fall perfectly on the regression line. The predictor x accounts for all of the variation in y!; If r 2 = 0, the estimated regression line is perfectly horizontal. The predictor x accounts for none of the variation in y!
