The objective of this study was to evaluate the use of the full hyperbolic function of three parameters, with the deletion and used the location as parameter function with minimum diameter and truncated to the right on the basis of maximum diameter to describe the diameter distribution of eucalyptus thinning. This study used data from an experiment on thinning. The permanent plots were measured at 27, 40, 50, 58, 61, 76, 87, 101 and 112, 125, 135, 147 and 160 months, with a first cutting out at 58 months and a second thinning at 130 months. All adjustments resulted in adherence to the data by the Kolmogorov-Smirnov (P> 0.01). The average values of the test were 0.0562, 0.0386, 0.0532 and 0.0387 for the function with three parameters, two parameters, location parameter equal to the minimum diameter and truncated to the right, respectively.
