A demonstration of how Excel’s Solver can be used to find the intercept and slope that minimize the sum of squared residuals can be found beginning in cell P1 of the sheet Dead in the workbook LMS.xls. The surface of the sum of squared residuals as a function of …

The least squares method chooses the values for b0, b2, … bk to minimize the sum of squared errors (SSE). In Excel use the LINEST array function to determine these estimates. Decomposition of variance. Y = Fit + Residual = Ŷ + (Y – Ŷ) Subtracting from both sides, (Y - ) = (Ŷ -) + (Y – Ŷ) Then, (Y - )2 = (Ŷ -)2 + (Y – Ŷ)2. i.e. SST = SSR + SSE. SST = Sum of Squares Total = (Y - )2. SSR = Sum of Squares …

Then find the squares of the x deviations as well as the square of the y deviations. Next calculate the product (multiplication) of the X and Y deviations. Obtain the sum of the last three calculations . We can finally now show from where Excel gets its slope of the best fit.

Our Excel spreadsheet now looks like this: The Solver function in Excel® is set up to minimize or maximize a cell in a spreadsheet. We will have Solver minimize the sum of the squares of the deviations between the actual viscosity data and the predicted values of viscosity.

The following example illustrates why this definition is the sum of squares. Example Sum of Squared Errors Matrix Form. To show in matrix form, the equation d’d is the sum of squares, consider a matrix d of dimension (1 x 3) consisting of the elements 2, 4, 6. Also, recall by taking the transpose, the rows and columns are interchanged.

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 minimize the sum of squared errors rather than the sum of the errors because in simply summing the errors, positive and negative errors can cancel each other out.

We will pick the values of and that minimize , the sum of the squares of the residuals. This method is often called Least Squares Regression. Here’s a picture of our data, showing the average selling price of all houses (the horizontal line at $88,840), the regression line (with a Y intercept of $18,354 and a slope of $3,879 for every 100 ...
