2. Suppose that a binary response variable Y is related to a set of predictors and a logistic model is fitted under sample size n= 8. Table.1 gives the observed y; and estimated probability ît; = Pr(Y; = 1) for each sample i, where i = 1,2,.., 8. Please sketch the ROC curve and calculate the area under the curve. (Hint: What if the cutoff TO = 0.55?)
