Example 3 –Interpreting Results of Multiple Regression Coefficients Table in Excel Coefficients:Coefficients are calculated using the least square method. In this example, the regression equation will be- y(Sales)=-1642.04 + 9.91*Unit Price + 8.13*Promotion ...
Dummy variables are assigned a value of "0" or "1". For example, in a time series regression of monthly stock returns, you could employ a "January" dummy variable that would take on the value of "1" if a stock return occurred in January and "0" if it occurred in any other month....

Multiple Linear Regression (MLR) is a powerful statistical technique widely used in finance and economics to analyze the relationships between multiple factors and a dependent variable. By understanding the formula and example provided in this blog post, you now have a foundation to apply MLR in yo...
It’s helpful to know the estimated intercept in order to plug it into the regression equation and predict values of the dependent variable: heart disease = 15 + (-0.2*biking) + (0.178*smoking) ± e The most important things to note in this output table are the next two tables – ...
When interpreting the results of multiple regression, beta coefficients are valid while holding all other variables constant ("all else equal"). The output from a multiple regression can be displayed horizontally as an equation, or vertically in table form. Example of How to U...
Example of How to Use Multiple Linear Regression (MLR) As an example, an analyst may want to know how the movement of the market affects the price of ExxonMobil (XOM). In this case, the linear equation will have the value of the S&P 500 index as the independent variable, or predictor...
So far we have considered only one regressor X besides the constant in the regression equation. Economic relationships usually include more than one regressor. For example, a demand equation for a product will usually include real price of that product in addition to real income as well as real...
The multiple linear regression estimates are computed by the StatCalc plug-in in Excel, as shown in table 2.2. Table 2.2 The equation for predicting efficiency is Y=13.182+0.5830.044+0.3290.057+0.1120.197 1X2X3X4X5X6X In Table 2.3, we use ten examples as validation data. Apply the pre...
