    We run the following linear regression model in Excel (or any other softwares) Yi = β0 + β1Xi + β2Wi + εi , where i = 1, 2, . . . , 100. The results suggest that the slope on Xi is 97.28 with t-statistics 0.91, and the slope on Wi is 15.81 with t-statistics 11.39. What does it tell us?

    4. In linear regression modeling, the regression line is sometimes known to go through the origin (0, 0), and x = 0 is within the scope of the model. In such case, we add the assumption that β0 = 0, so the regression model reduces to: Yi = β Xi + εi . (The assumptions about ε remain the same). (Note: Since now there is only one parameter, we simply denote it β instead of β1 ). (a) Derive the...
