Abstract

This study aimed to estimate the height of the diameter at breast height by adjusting mathematical equations in a Pinus taeda L. population in the municipality of Eneas Marques, PR. For this, we conducted a forest inventory through systematic sampling. In each plot was carried out to measure the circumference at breast height of all individuals , and the overall height of only 30 % of them , and other times estimated by the chosen equation. To adjust the hypsometric models was used PROC REG procedure , where ten mathematical models were tested . Of these models were selected that showed the best results of the adjusted determination coefficient, coefficient of variation , calculated F , standard error of the estimate and graphical analysis of waste. Best model chosen was , presenting an adjusted coefficient of determination of 0.7419 a 8.89 coefficient of variation and the best and highest value of F of 1722.95 and a standard error of 0.02.
