Abstract

This paper presented the development of a simple model for obtaining the stem volume of a tropical tree species, that is, Cinnamomum iners based on the two volumetric equations, namely, the Huber's and Newton's equations. Variables considered during data collection were height of stem or trunk, height of tree, diameter at breast height, diameter at middle and diameter at top of the stem before the crown. Correlation tests were done to screen and select these possible variables with their interactions. The eight criteria model selection(8SC) process was also done to obtain the best model. However, the best model was found to be in the form of multiple regressions (MR) of interactions up to the fourth order.
