Question 5: Prediction (9 points) Note: Use “testData” for all questions in Q5 5a)(6 points) Using the testData, predict the monthly energy consumption for each of the models below: i) model2 (question 2b) ii) model3 (question 3b) iii) model4 (question 4c) Calculate the precision measure for predictions of all the models. Which model performed the best according to the precision measure? Why do we focus on the precision measure? Q5b) (3 points) Extract the first row of testData. Using model2, what is the 99% prediction interval (PI) of the monthly consumption of energy (kWh)? Provide an interpretation of your results.
