metadata.revistascielo.dc.description: The purpose of this study was to evaluate the theory of the generalized mixed models and the modeling of the heteroscedasticity of variance in the fit of two nonlinear models for the height-diameter relationship in Eucalyptus sp. Data from sample trees of different genotypes (clone and seed) and ages were used. According to the analysis, the asymptotic model achieved the best results compared to the sigmoid model. The accuracy of the models increased using the theory of mixed effects with the addition of covariates and modeling of the heteroscedasticity of variance.
