Abstract

The objective of this study was to evaluate the efficiency of the log-gamma function to describe the diameter structure of even-aged stands and propose a diametric distribution model using the function. The function was fitted to data from permanent plot inventory, measured at six different ages. The function´s adherence to the data was confirmed by the Kolmogorov-Smirnov test. The graphical analysis of residuals showed no bias for the models built. The log gamma function can be used to build models of the diameter distribution of eucalyptus.
