| Abstract: | This article collects the sample materials of 38 trees of Cunning-hamia lanceolata and proceeds from the smallest residual error quadratic sum ofthe volume to analyze and study the parameter optimization problem of binaryvolume equation with the simplex method and the weighted least square methodrespectively. The results indicate that both methods which can effectively reducethe residual error quadratic sum of the volume and optimize its parameter valuesare one of the effective ways of improving the precision of binary volume table. |
