Q3. Decisiоn Tree аnd Rаndоm Fоrest Models (17 points) (10 points) а) Using the dataset "trainData", fit the following classification models below using all the predictors in "trainData" and "Completed" as the response variable. i) Decision Tree Model (call it model_dt). ii) Random Forest Model (call it model_rf). Use metric = “Accuracy”, trControl = trainControl(method=“cv”, number=5) for both models. Display the summary of both models and state the average accuracy, sensitivity and specificity for both the resampled models. Interpret "Accuracy", "Sensitivity" and "Specificity" values and explain your overall conclusion about the models. Which model performs better? (4 points) b) Using testData, predict the probability of a student completing the course, and output the average of these probabilities for each of the models below: i) Decision tree model (model_dt) ii) Random forest model (model_rf) (3 points) c) Using decision tree model, what is the overall predicted completion rate in the test dataset? How does it compare to the training dataset? Note: Note: Use threshold=0.5 for converting the probabilities into binary.
