The objective of this work was to test the probability function for growth and yield modelling. The data came from 325 permanent samples established in unthinned Pinus taeda L. (loblolly pine) stands owned by the International Paper of Brazil Co. It was used functions for dominant height, site, mortality, basal area and variance of the diameters. The Weibull probability distribution chosen to be used was fitted to data by the moments method. Seventy sample plots were randomly chosen in order to make the comparison among the observed and predicted values. In general, the probability function provided satisfactory estimates for number of trees, basal area and stem volume per hectare.
