Use the tоy dаtа set here fоr this prоblem. Regress Y on X1, X2, X3 аnd X4. a) Create a boxplot for Y. Are there any outliers based on your boxplot? [a_no]. b) Construct scatterplots with Y against the various explanatory variables. Based on the scatterplots which variable appears to have the least clear relationship with Y? [b_X2]. c) Regress Y on X1, X2, X3 and X4. Suppose the data are from some economic study as opposed to a study in biology or physics. Given a business or economic setting for the data, can the R2 be called "large"? [c_yes]. d) Which variable or estimated variable coefficient, shows the greatest statistical significance based on the regression results? [d_X1]. e) This is not a trick question. There are "good" and "bad" models. True or False: the F statistic, the t statistics and the R2 value give the initial impression that this is a good model. [e_true]. f) Examine the standardized residuals. Create a histogram, a QQ plot or use the default QQ plot and conduct a Shapiro-Wilk test. Choose the best statement. (i) Based on the Shapiro-Wilk test you reject the assumption of normally distributed errors at the 0.05 level (ii) Based on the Shapiro-Wilk test you fail to reject the assumption of normally distributed errors at the 0.05 level. [f_4]. g) Use the plot() command to examine the default plots of the residuals. True or False: based on the graphs there is at least one observation with leverage greater than 0.5. [g_false]. h) Use the graphs from part (g) for this question. Do not consider any information related to these data or this model not provided in the default plots. True or False: there is at least one highly influential observation. [h_true]. i) Consider again the F statistic, the t statistics and the R2 value and your histogram of the residuals, the result of the Shapiro-Wilk test, and the plots from part (g). Suppose that you are building a model in order to make predictions about out of sample values. Based on all this you conclude: (i) no adjustments are needed to have reasonable predictions or forecasts (ii) for relatively high predicted values (forecasts) you anticipate that the actual values will be higher than your model's predicted values (iii) because the residuals are not normally distributed your model cannot be used to make predictions (forecasts) (iv) the actual out of sample values will be between 88% and 112% of the predicted (forecasted) values. [i_ii].
