Compute the support for itemsets {P}, {Q, S}, and {P, Q, S} by considering each TID as a market basket. b. Use the results in a. to compute the confidence for the association rules (QSP), and (P QS). Is confidence a symmetric measure? c. Assuming minimum support=0.4, use the Apriori algorithm to generate all the frequent itemsets. d. Generate all the association rules for the frequent 2-itemsets obtained in c. Calculate the confidence for the rules.
