Comparison of Similarity Coefficients on Morphological Rodent Tuber

摘要

Many comparisons of similarity coefficient done by researchers, especially in the field of biology. This comparison aims to find the most appropriate similarity coefficient for some cases. Many results found that Sorensen-dice coefficient and Jaccard coefficient is close or even identical. But Jaccard coefficient can not handle properly for sets with real-value or weighted sets or any pair of vectors. So, Jaccard coefficient redefined as Generalized Jaccard Coefficient. This paper shows the correlation between Sorensen-dice coefficient with Generalized Jaccard Coefficient using Spearman's correlation as predecessors research did and using ANOVA to ensure the results. This research find that the comparison between them is less similar from predecessors research.
