association rule mining example

If we apply an association rule mining algorithm, it will return all the rules having a support and confidence respectively no less than minsup and minconf. For example, by applying the algorithm with minsup = 0.5 (50%), minconf = 0.6 (60%), we obtains 55 associations rules ( run the example in the SPMF distribution to see the result ).
