Use the tоy dаtа set here fоr this prоblem. а) What is the mean of Y? [a_pt4366]. b) What is the standard deviation of T? [b_5pt76]. c) Construct a boxplot of U. Based on the boxplot, how many outliers are there? [c_2]. d) Run a logistic regression with Y as the dependent variable and T, U and V as the explanatory variables. What is the estimated coefficient on T? [d_negpt899]. e) Construct a 90% confidence interval for the coefficient on T. Choose the values for the interval. [e_neg1pt444]. f) At the 0.05 level of significance test the hypothesis that the coefficient on U is 1. You [f_failtoreject]. g) What is the concordance for your regression? [g_pt9758]. h) What is the estimated probability that Y=1 when T= 17 and U = 17 and V= 27? [h_pt9709]. i) What is the log odds for that scenario? [i_3pt509]. j) Which observation has the most "unexpected" outcome? That is the observation where the outcome was least consistent with the probability of success assigned by the model. [j_56].
