Sсhorygin similarity coefficient for a series of samples
This online calculator allows you to use a table of species distrubution in samples to calculate the Schorygin coefficient (or commonality coefficient of specific abundance) in pairs for each pair in a series of samples.
Jaccard index
The Jaccard index refers to binary similarity coefficients and is a commonly used measure for analyzing the species composition of communities or samples in biological studies. This similarity measure is the intersection of sets. The calculator is designed primarily for biologists, but is universal for estimating the intersection of sets and can be applied to other, non-biological problems.
