Use the tоy dаtаset here fоr this questiоn. а) Plot the Y variable against the three X variables and find their correlations. Y appears to be most strongly correlated with which variable? [a_X3]. b) Regress Y on X1, X2 and X3. What is the estimated variance of the error term? [b_1pt96]. c) Are there any influential observations? [c_no]. d) Perform a Box-Cox analysis for the model. Given the answer options, what transformation is recommended for Y? [d_sqrt]. e) Perform a Box-Cox analysis where X1 is the dependent variable and Y is the independent variable. Note that this is a different model than the model from part (b) and in this case you are using X1 as the response variable. What is the transformation that the Box-Cox analysis recommends? [e_none]. f) Regress Y on the natural log of X1, the natural log of X2 and X3. Note that two of the explanatory variables involve log transformations while one does not. Does this model have greater explanatory power than the model in part (b)? [f_no]. g) For the model in part (f), test the hypothesis that the coefficient on log(X2) is equal to 0.2. What is the test statistic for this test? [g_negpt276]. h) For the model in part (f) test the hypothesis that the coefficient on log(X1) is equal to 1 at the 0.05 level of significance. State the p-value and your conclusion. [h_pt458].
