WebbGower’s similarity coefficient; it is appealing because ranges between 0 and 1, being an average of the scaled distances calculated variable by variable. In addition, the Gower’s distance handles missing values and allows for a user-defined weighting scheme when averaging distances. The WebbThe overlap coefficient is a similarity measure related to the Jaccard measure that measures the overlap between two sets, and is defined as the size of the intersection divided by the smaller of the size of the two sets. For two sets X and Y, the overlap coefficient is: o v e r l a p _ c o e f c i e n t ( X Y) = X ∩ Y min ( X , Y ) Note
