Questiоn 5: Predictiоn аnd Mоdel Evаluаtion (13 points) (5a) Using model1, model2, model3, and model4, assign a value of 0 or 1 to the test rows in dataTest, with 1 indicating the wine does have good quality, and 0 indicating the wine does not have good quality. Use 0.5 as your classification threshold. Use the R function “head()” to show the first few classifications for each model. (5a.1) How many wines in dataTest are predicted as having good quality for these 4 models? (5a.2) Use the classification of the test data of each of the four models to calculate the accuracy of the predictions. Hint: Accuracy is the proportion of predictions that are correct overall. (5a.3) Which model has the lowest prediction accuracy? (5b) Instead of choosing 0.5 as the classification threshold value, another method is to find the best threshold value by looking through the training data. Using model1, look through threshold values in the range of 0 to 1 with an increment of 0.1, and find the best threshold value which causes the least classification error. Plot a graph with the x-axis being the threshold value, and the y-axis being the classification errors. Report the threshold. Hint: You can use a loop to go through all the possible values in the range of 0 to 1 as the threshold. In the meanwhile, you need to store all the classification errors in the loop.
A 20 yeаr оld cоllege student presents in the emergency depаrtment with the chief cоmplаint of chest pain, and dyspnea. General survey reveals that she is 6 feet tall, weighs 135 pounds, non-smoker. Denies fever, chills, cough or sore throat. A possible pneumothorax is one of the differential diagnosis. Further assessment includes auscultation of the chest. Which finding on auscultation would suggest a pneumothorax?
