In the similarity indices included in this study: a = the number of species in sample 1 b = the number of species in sample 2 c = the number of species in common between 1 and 2 d = the number of species absent in both 1 and 2 k = the number of species in 1 and 2 combined = a + b - c.

To calculate the similarity index, the weight (in pounds per acre) of each species (or species) group is recorded for a site. The allowable production of a species or species group cannot exceed that of the reference community. The similarity index is then determined by dividing the total allowable production The Structural Similarity (SSIM) Index quality assessment index is based on the computation of three terms, namely the luminance term, the contrast term and the structural term. The overall index is a multiplicative combination of the three terms. 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. The similarity coefficients proposed by the calculations from the quantitative data are as follows: Cosine, Covariance (n-1), Covariance (n), Inertia, Gower coefficient, Kendall correlation coefficient, Pearson correlation coefficient, Spearman correlation coefficient.
