Jaccard / Tanimoto coefficient is one of the metrics used to compare the similarity and diversity of sample sets. It uses the ratio of the intersecting set to the union set as the measure of similarity. Thus it equals to zero if there are no intersecting elements and equals to one if all elements intersect.
Equation for Jaccard / Tanimoto coefficient is
- number of elements in set А
- number of elements in set B
- number of elements in intersecting set
How to use it - enter elements, separated by comma, and calculator outputs coefficient and intersecting set (for reference)
