The volume is simply calculated as the sum of each beams length multiplied by the thickness squared (square cross-section assumed). Therefore, although the volume was an objective function, it was over-constrained and the Pareto surface plots below were the result.

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.

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. The interpretation of equation (2) is now clear.

How does Excel determine the "best fitting" line? Excel chooses the line that minimizes (over all lines that could be drawn) the sum of the squared vertical distance from each point to the line. The vertical distance from each point to the line is called an error, or residual. The line created by Excel is called the least-squares line.

We divide the sum of squared errors by n-2 to obtain an unbiased estimate of (recall how you computed a sample variance when sampling from a single population). ... Rules for standard errors and tests are given in the next chapter. We will mainly use SAS, EXCEL, and SPSS throughout the semester. EXCEL (Using Built-in Data Analysis Package ...

Writing the equation for the sum of squared errors and using elementary calculus, one can find the values of b; 0 and b 1: that minimize the error, and guarantee the “best fitting” line through those points. You can refer to any basic statistics book for the formulas.
