A NEW TOTAL CUBIC FOOT VOLUME FUNCTION

Abstract

The problems involved in constructing volume tables are briefly discussed. Nine functions were evaluated, and the transformed variable function [Formula: see text] selected to express the volume-diameter-height relationship.In developing the function, the relationship between [Formula: see text] and [Formula: see text] was accepted as being linear in form, permitting graphical or least squares solution. No special weighting procedures were required as the transformation tends to equalize variances over the range of data.The function provided accurate estimates, and volume errors were independent of tree size. The methods used to estimate tree and stand volumes are briefly described. (Oxford Classification 524.2)
