Abstract

The main purpose of this study was to develop a linear mixed-effects model to estimate the basal area growth and yield, for clonal Eucalytus stands. After modeling the variance among sample plots and clones, it was verified a significant improvement of the statistic information parameters (AIC and BIC) and the likelihood logarithm value. Also, after modeling both heteroscedasticity and autocorrelation, such statistic criteria had a significant improvement. Thus, the modeling process improved significantly the estimated parameters in the linear model.
