Once you have the idea and the data, it is time to apply the LRM. Some issues you should inves- tigate and discuss are: o Are the variables that you thought could be important statistically signicant (at 5%)? o Are there variables that you would have liked to include in the regression but could not nd data for? Discuss Whether you expect these omitted variables to introduce bias in your OLS estimates. 0 Are the estimated effects (betas) of the expected sign? 0 Interpret the estimated effects 0 Are there one or more variables that you would like to exclude from the regression because they are irrelevant? Use the Ftest 0 Include at least one type of nonlinearity in the LRM and interpret its effect
