###### Answer the following questions:1 A data mining routine has been applied to a transaction dataset and has classified 88 records as fraudulent (30 correctly so) and 952 as non- fraudulent (920 correctly so). Construct the classification matrix and calculate the error rate, sensitivity, and specificity: 2. Suppose that this routine has an adjustable cutoff (threshold) mechanism by which you can alter the proportion of records classified as fraudulent: Describe how moving the cutoff up or down woul

Answer the following questions: 1 A data mining routine has been applied to a transaction dataset and has classified 88 records as fraudulent (30 correctly so) and 952 as non- fraudulent (920 correctly so). Construct the classification matrix and calculate the error rate, sensitivity, and specificity: 2. Suppose that this routine has an adjustable cutoff (threshold) mechanism by which you can alter the proportion of records classified as fraudulent: Describe how moving the cutoff up or down would affect Sensitivity, specificity, true negative, and true positive:  #### Similar Solved Questions
