摘要
对实验变差函数理论模型的自动拟合是地质统计学中的一个难题。结合加权多项式法和线性规划法的优点 ,对线性规划法进行改进 ,提出用滞后距倒数为权系数的线性规划法进行球状模型的参数估计 ,并给出了计算实例。应用该方法可以得到一个统一的。
The automatic fit of experimental variation functions is a difficult problem of geostatistics In combination of weight polynomial method with the advantages of linear programming, an improvement is made on the linear programming method,the parameters of a spherical model are estimated by using the linear programming method which uses the reciprocal of lag distances as weight,examples of calculation are also given A uniform,objective estimation of optimal parameters is obtained by using this method
