- Figure 1 shows the general discriminatory test for health status prediction. "Perfect test cut-off True negative; TN (specificity) True positive; TP (sensitivity) False negative (FN) False positive (FP) Healthy Sick (a) Test cut-off Moving cut-off to left reduces false negatives (higher specificity) at cost of reduced sensitivity Moving cut-off to right reduces false positives (higher sensitivity) at cost of reduced specificity TN TP FN FP Healthy Sick (b) Figure 1. The Discriminatory Test with (a) A Good Discrimination Test Cut-off, and (b) A Bad Discrimination Test Cut-off i. What is your next action, if you obtain a perfect discriminatory test result (where both false negative and false positive rate are near zero) during model training? Justify your action. ii. In which phase of machine learning methodology do you move the test cut-off point as shown in Figure 1(b)? Justify why you should do that.Use the minimax regret and Hurwics (α=0.8) to assist Susan with her decisionWhich of the following is not a lead indicator used in balanced scorecards?

Suppose that Bone Ranch Wave has scores in these categories of 4, 5, 3, 8, and 9, respectively. What is its rating?A) 5.80 B) 5.00 C) 7.60 D) None of the previousChoose which criteria give the most promising result? Are these criteria often accurate? maximac criterion maximin Criterion Minimax regret criterion Hurwicz Criterion Equal likelihood criterion(c) Based on what we know about Observation B, if the cutoff value is lowered to 0.2, what happens to the values of sensitivity and specificity? Explain. Use the ROC curve to estimate the values of sensitivity and specificity for a cutoff value of 0.2. If required, round your answers to three decimal places. Do not round intermediate calculations. Answer Part C, there are no other parts here. I have the sensitivity already and is equal to 1. What is the specificity??If you are not 100% sure you are right, do not attempt this is frustrating. The cutoff value has changed from 0.5 to 0.2. The sensitivity is 1 which is correct. I need help with the specificity. Sensitivity does not equal 1/14 and specificity does not equal 1/31 so don't answer that and do not answer any other parts just answer part C.
