Diversity indices to test the goodness of fit to the broken stick distribution
In this paper, we present the Shannon diversity index, the Shannon exponential index and the Margalef diversity index to test the goodness of fit to the broken stick distribution in several populations. The chi-squared test is the most common test to fit the broken stick distribution, but it has several problems. With an example, we show a situation in which a test based on diversity indices improves the results obtained by using the chi-square test.
Keywords: broken stick, diversity indices, goodness of fit.
