Option #1k-Nearest Neighbor

Suppose you work for a wine company as a data mining expert. You are to build a k-nearest neighbor algorithm to predict the quality of wine from different factors. Download the dataset calledwinequality-red.csv(Links to an external site.)

from Module 4 and then perform the following tasks. The data description is provided in the file calleddescription-winequality-red.docx(Links to an external site.)

.

1. Provide the summary statistics for all the variables from the dataset. Explain some of the key aspects of the dataset.
2. Examine the SAS code frommod4knn.sas(Links to an external site.)
3. file and for each SAS statement, provide the explanation of the code as SAS comments. Put this part in the Appendix of your report.
4. Perform the k-NN using k = 1, 2, and 3. For each case, explain the SAS output and give interpretation(s).
5. Which case (k = 1, 2, or 3) provides the best model? Explain why using the output from part c.

Take the screenshots of SAS output and paste them into a Word document. Include all relevant calculations and your responses to all items (1, 2, 3, and 4) and submit the document to Canvas for grading. Clearly label all elements in your submission. In addition, provide a short description of any challenge(s) you faced during this assignment.
