摘要：

The objective of this work was to assess the fitting quality of the diameter distribution modeling of an even-aged stand of eucalyptus, according to the variation in the diameter class range. Both the function fitting to the observed data and the projection of the function parameters were evaluated, using a diametric distribution model. Data from 48 permanent plots, obtained at four occasions, was used. Statistical equivalence between the observed distributions and the estimated ones by the Weibull function were evidenced in all situations. The Weibull function fitted properly to the observed data independently of class range; however, the theoretical redistribution of diameter per class, using a diametric distribution model, was affected by class range.
