建立材积方程时,通常根据得到的原始数据和选定的材积方程形式,用通常最小二乘法(OLS)对其相应参数进行估计。对得到的材积方程进行显著性检验,以此方程为基础进行预测和估计材积。本文就建立材积方程时应注意的两个数学问题,提出来和大家讨论。
When building the volumetric equation, the corresponding parameters are usually estimated using the usual least-squares method (OLS) based on the raw data obtained and the volume equation of choice. The obtained volume equation was tested for significance and the equation was used as a basis for prediction and estimation of volume. This article discusses the two math problems that should be noticed when building the volume equation.
