Description
1. Download the breast-cancer-dataset.csv from your D2L Assignment 1 link.
Complete the following tasks (5 points):
a. Read the file in SAS and display the contents using the import and print
procedures. (1 point)
b. Develop a decision tree-based classification model using the hpsplit
procedure of SAS. (2 points)
c. Navigate the contents of Results View by clicking on HPSplit breastcancer-dataset, and then by selecting Model Assessment. Examine the
confusion matrix, fit statistics, and variable importance. (2 points)
2. Using the confusion matrix, compute the following assessment metrics accuracy,
recall, and precision (see lecture for formulas). (5 points)
Condition for marks: 3 points for accuracy, 1 point for precision, and 1 point
for recall.
3. Change the grow algorithm to “gini” and recompute the metrics from question 2.
Does entropy build a more accurate classifier or gini? (5 points)
