SSTO = total sum of squares. SSE = sum of squared errors (remaining variability of Y not explained by the X1,…,Xp-1) SSR = regression sum squares (variability of Y accounted for by the X1,…,Xp-1) SSE can be calculated for different sets of variables . SSE(X1) = Sum of squared errors using only X1 in the model (Yi=(0+(1X1i+(i)

Total sum of squares = sum of squares due to regression + sum of squares about regression: TSS SSDue SSAbout (aka error, ε) R2, or the coefficient of determination, is defined as the percent of variation in Y about it’s mean that is explained by the linear influence of the variation of X.

With these elements, the sum of squares equals 22 + 42 + 62 = 56. In matrix notation, d and d’ are. The sum of squares equals. This shows multiplying the transpose of a vector by the vector will give the sum of squares of the vector. With the sum of squared residuals defined and using the definition for calculating the error term, the objective function of OLS can be written as follows: (11) .

This is sometimes called the total variation explained by the regression. SSE stands for “sum of squares due to error” - this is simply the sum of the squared residuals, and it is the variation in the Y variable that remains unexplained after taking into account the variable X. …
