Quantitative methods in ethnobotany and ethnopharmacology: considering the overall flora-hypothesis testing for over- and underused plant families with the Bayesian approach


Weckerle, C S; Cabras, S; Castellanos, M E; Leonti, M (2011). Quantitative methods in ethnobotany and ethnopharmacology: considering the overall flora-hypothesis testing for over- and underused plant families with the Bayesian approach. Journal of Ethnopharmacology, 137(1):837-843.

Abstract

Testing for over- and underused taxonomic groups of a flora with the Bayesian method is easy to adopt and can readily be calculated in excel spreadsheets using the excel function Inverse beta (INV.BETA). In contrast to the binomial method the presented method is also suitable for small datasets. With larger datasets the two methods tend to converge. However, results are generally more conservative with the Bayesian method pointing out fewer families as over- or underused.
