WebJaccard Distance. A similar statistic, the Jaccard distance, is a measure of how dissimilar two sets are. It is the complement of the Jaccard index and can be found by subtracting the Jaccard Index from 100%. For the above example, the Jaccard distance is 1 – 33.33% = 66.67%. In set notation, subtract from 1 for the Jaccard Distance: WebJaccard's coefficient can be computed based on the number of elements in the intersection set divided by the number of elements in the union set Of course, the set formula is also work for binary data, but we need to …
