Abstract:The objective of this work was to compare methods of obtaining the site index for eucalyptus (Eucalyptus spp.) stands, as well as to evaluate their impact on the stability of this index in databases with and without outliers. Three methods were tested, using linear regression, quantile regression, and artificial neural network. Twenty-two permanent plots from a continuous forest inventory were used, measured in trees with ages from 23 to 83 months. The outliers were identified using a boxplot graphic. The arti… Show more
“…In the Trimmed mean method, the data is sorted in ascending order and the median value is calculated (Júnior, et al (2019)). Then, the outliers are estimated based on their size relative to the rest of the data as follows:…”
