Abstract

Abstract

This research aimed to evaluate the behavior of seven probability density functions for fitting the diameter distribution of Escheweilera ovata in a Dense Ombrophilous Forest fragment in the State of Pernambuco, Brazil. The data used consisted of diameters of 274 trees of this species measured during a research improved to evaluate the tree components and succession classification of this fragment. The following probabilistic functions were tested: Beta, Gamma, Log-Normal, Normal, Johnson SB , Weber and Weibull 3P, it was used diametric class interval of 4 cm. The results of the Kolmogorov - Smirnov test indicated that the most efficient function was the Log-Normal, followed by Weber, Weibull 3P, Johnson SB , Beta, and Gama. The Normal distribution was rejected by the Kolmogorov - Smirnov test. This research also indicated that the Escheweilera ovata diameter distribution in this fragment is decreasingly.

Keywords: Probabilistic distributions; native forest; inverted “J”.
