Given the association rule X->Y, _________ is the ratio of the expected frequency of Y doesn’t occur to the frequency of X occurs and Y does not occur.

Select one:

a. Support

b. Confidence

c. Lift

d. Gain

e. Conviction

Homework Answers

Answer #1

Answer: option e

conviction

Beacause conviction is ratio of the expected frequency where x occurs and y doesn't occurs

And rest of the options are wrong because

Support is the representative of or indication of how frequently itemsets appear in data set

And confidence is about how often the rule is true

And lift is ratio of observed support to the expected support if x and y are independent.

And gain is different from the condition of the association rule given
