The following table demonstrates the predicted values by models and actual values Based on RMS error determine which model is better? Actual value 120 Model 1 183 618 163 455 Model 2 1816 161655 Person Person 2 DF Person 2 163.455 163.455 16 168 Question 4 10 Marks The table below represents the values of x (fork-lift driving experiences in years) and y (monthly insurance in dollar) x 5 64 2 87 12 50 9 71 15 44 6 56 25 42 16 60 Find the least square regression line b. Calculate and critically comment on the value ofr andr MITS6002-Business Analytics Question 5 05 Marks Imagine that we have a collection of photos of CT scan images of head. Each photo shows one Image of head: either front, middle, or back. Our classifier needs to predict which image is shown in each photo. This is a classification problem with N=3 classes. A confusion matrix is shown below: True/Actual Middle 6 Back Front 4 1 1 Front Middle Back 2 3 0 6 Predicted 2 a Determine the recall and precision of the classifier for front, middle and back image. b. Discuss the classifier's performance in terms of recall and precision values.
