This January 2009 help sheet gives information on You can also create a scatter plot of these residuals.EXCEL 2007: Two-Variable Regression Using Data Analysis Add-in EXCEL 2007: Two-Variable Regression Using Data Analysis Add-in A. For example, the first data point equals 8500. The residuals show you how far away the actual data points are fom the predicted data points (using the equation).

For example, if price equals $4 and Advertising equals $3000, you might be able to achieve a Quantity Sold of 8536.214 -835.722 * 4 + 0.592 * 3000 = 6970. You can also use these coefficients to do a forecast. For each unit increase in Advertising, Quantity Sold increases with 0.592 units. In other words, for each unit increase in price, Quantity Sold decreases with 835.722 units. The regression line is: y = Quantity Sold = 8536.214 -835.722 * Price + 0.592 * Advertising. Once the appraiser has the download, he or she, would open up Davids application to import the data into a 'Raw Sales' workbook and then 'Scrub' the data in preparation for analysis. Most or all P-values should be below below 0.05. Part 1 of the introduction to Regression Analysis, starts off with MLS data exported to a standard Excel spreadsheet. Delete a variable with a high P-value (greater than 0.05) and rerun the regression until Significance F drops below 0.05. If Significance F is greater than 0.05, it's probably better to stop using this set of independent variables. If this value is less than 0.05, you're OK.

To check if your results are reliable (statistically significant), look at Significance F ( 0.001).
