Association Rules (10%) This item requires the dataset Cosmetics-small.xls which can be found on the subject Interact site. Using XLMiner, apply association rules to the file Cosmetics-small.xls. Note: Do NOT include the Transaction # column in the XLMiner Data Range and accept the default Minimum Confidence (%) of 50. i. Interpret the first three rules in the output (in your own words). ii. Reviewing the first couple of dozen rules, comment on the rules’ redundancy and how you would assess the rules’ utility. iii. What would be the impact to the resulting rules if the Minimum Confidence (%) was raised to 75? Discuss why this occurs. 2. Cluster Analysis (10%) This item requires the dataset EastWestAirlinesCluster.xls which can be found on the subject Interact site. The dataset EastWestAirlinesCluster.xls contains informati************ pass************ belong to an airline’s frequent flier program************ pass************data include information on their mileage history and on different ways they accrued or spent miles in the last year. The goal is to try to identify c************ pass************t have similar characteristics for the purpose of targeting different segments for different types of mileage offers. a) Apply hierarchical clustering with Euclidean distance and Ward’s method. Make sure to normalize the data first. How many clusters appear? b) What would happen if the data were not normalized? c) Compare the cluster centroid to characterize the different clusters, and try to give each cluster a label. d) Use K-means clustering with the number of clusters that you found above. Does the same picture emerge? e) Which clusters would you target for offers, and what types of offers would you target to customers in that cluster?
