Resumo: The present study aimed to evaluate the Box-Cox transformation performance in dendrometric relationship prediction of open-grows-trees at Minas Gerais Cerrado. For each tree were measured the diameter at 0.3 (d0.3), 0.7 (d0.7) and 1.3 m (d) above ground, as well as total height (h), base crown height (cbh), crown length (cl) and crowd diameter (cd). In cases of forked stems were calculated the equivalent diameter (deq). The description of dendrometric relationships using the diameter at 1,3 m above the ground were compared by adjusted models with and without Box-Cox transformation. A total of 193 trees were measured, belonging to 29 botanic families and 56 species. According to the Kolmogorov-Smirnov, Breusch-Pagan and Durbin-Watson tests, no traditional equation attended the regression assumptions, although, after the Box-Cox transformation some of them attended. The adjusted equation using the Box-Cox transformation presented precision increase in the estimation, principally for the variables d0.3, d0.7, h and cd. Box-Cox transformation can be used to the data check or at least improve the statistics of the regression assumptions.

Em cada árvore foram medidos os diâmetros à 0,3 (d0,3); 0,7 (d0,7) e 1,3 m (d) do nível do solo, assim como altura total (h), altura de inserção de copa (hic), comprimento de copa (cc) e diâmetro de copa (dc). Em casos de perfilhamento do fuste foi calculado o diâmetro equivalente (deq). A descrição das relações dendrométricas utilizando como variável preditora o diâmetro à 1,3 m acima do nível do solo (d) foi comparado com o ajuste de modelos com e sem a transformação Box-Cox. Um total de 193 árvores foram amostradas, pertencentes a 29 famílias botânicas e a 56 espécies. Segundo os testes de Kolmogorov-Smirnov, Breusch-Pagan e Durbin-Watson, nenhuma equação tradicional atendeu os pressupostos da regressão, porém, após a transformação Box-Cox algumas delas atenderam. As equações ajustadas com a utilização da transformação Box-Cox apresentaram aumento na precisão das estimativas, principalmente para as variáveis d0,3, d0,7, h e dc. A transformação Box-Cox pode ser utilizada para que os dados atendam ou ao menos melhorem as estatísticas dos pressupostos das regressões.Universidade Federal de Minas Gerais2021-08-23info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/htmlhttps://periodicos.ufmg.br/index.php/ccaufmg/article/view/3340110.35699/2447-6218.2021.33401Agrarian Sciences Journal; Vol. 13 (2021); 1-9Caderno de Ciências Agrárias; v. 13 (2021); 1-92447-62181984-6738reponame:Caderno de Ciências Agrárias (Online)instname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMGporhttps://periodicos.ufmg.br/index.php/ccaufmg/article/view/33401/29843https://periodicos.ufmg.br/index.php/ccaufmg/article/view/33401/29844Copyright (c) 2021 Caderno de Ciências Agráriashttp://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccess Bueno, Gabriel Fernandes Costa, Lidiomar Soares Costa, Emanuel Arnoni2022-07-20T21:35:43Zoai:periodicos.ufmg.br:article/33401Revistahttps://periodicos.ufmg.br/index.php/ccaufmgPUBhttps://periodicos.ufmg.br/index.php/ccaufmg/oaiccaufmg@ica.ufmg.br2447-62181984-6738opendoar:2022-07-20T21:35:43Caderno de Ciências Agrárias (Online) - Universidade Federal de Minas Gerais (UFMG)false
