A store manager is interested in finding patterns between the
items A, B, C, and D in the store. The transaction matrix is
below:
a. List all frequent itemsets, and their respective support
values, which have at least 20% support.
b. Suppose a customer buys item A. What is the
probability that he will also buy item B? Show your
calculations.
c. Suppose a customer buys item C. Which other
item is she most likely to buy? Why?
d. Suppose one unit of item A sells for $20 and one unit of
item B sells for $10. Further, you can either place item A next to
item C or place item B next to C, BUT NOT BOTH. Is it more
profitable to place item A next to C or item B next to
C? Explain.
e. For anyone who buys A, we can recommend B, and vice
versa. Which recommendation is more likely to be successful, and
why?
