Consider the accompanying data file to estimate the logistic regression model for predicting college admission (Admit equals 1 if admitted, 0 otherwise). Predictor variables include the applicant’s grade point average (GPA) and scores on the SAT test. Use the holdout method, using the first 90 observations for training and the remaining 30 observations for validation, to calculate and interpret the accuracy, sensitivity, and specificity measures.
