Abstract

Five non-segmented taper functions were modeled for Tectona grandis, which has increased significantly their planted area in Coastal Ecuador were formulations of this type are unknown. A process of nonlinear regression (maximum likelihood) was performed to a sample of 125 trees with fit evaluation. Subsequently, an independent validation process were performed, non parametric tests and a relative height analysis in order to identify strengths and weaknesses in each part of the shank was also applied. The fifth grade polynomial function showed the best fit (Absolute Bias = 1.009, Fit Index = 0.962), for that reason, the integrated form of this equation was calculated. It is expected that these developed models and their application benefits could be useful for the forestry comunity in Ecuador.
