Download the data set Benign, which is Table 15.29, from the textbook website. The variable cancer is a dummy variable, where 1 = had breast cancer and 0 = did not have breast cancer.* Using the variables age (= age of subject), HIGD (= highest grade completed in school), CHK (= 0 if subject did not undergo regular medical checkups and = 1 if subject did undergo regular checkups), AGPI (= age at first pregnancy), miscarriages (= number of miscarriages), and weight (= weight of subject), perform a logistic regression to conclude if these variables are statistically useful for predicting whether a woman will contract breast cancer or not.
