It is then easy to ensure that h' (the rate of change of height with age), approaches zero as t approaches infinity.

Chapter 5: A Study on Chapman Richards Growth Model
WebEquations for estimating stem volume, stand volume and site index were developed as part of an effort to quantify growth and yield of natural stands of Pinus patula in its native range in Mexico. Data were collected from 162 plots in 54 different stands. A Chapman-Richards equation was fitted to dominant height and age to derive a family WebThe Chapman-Richards' equation presented random outlines of residual around zero and no obvious signs. Thus, there is no serious failure of homoscedasticity, violations of the assumption of... WebThe Chapman-Richards equation was derived from the Bertalanffy equation "When limitations imposed by its theo- retical background are discarded" (Richards 1959). Parameter m in the equation was assumed to be positive, not only in range of 0 < m < 1 as in Bertalanffy's case.
