weighted least squares method meaning in Chinese
加权最小二乘法
Examples
- Two - stage - fitting ( tsf ) method is obtained , which consists of evaluating the function values of regular - grid points by using local weighted least square methods or radial function interpolation , and smoothly and quickly interpolating those points by using multivariate splines . the result is a hyper - surface of c1 or c : continuity
基于上述结果，提出了h - d空间散乱数据超曲面构造二步法，第一步应用局部最小二乘法或局部径向基函数拟合法插补立方体网格点上的函数值，第二步应用多元样条光滑快速插值计算，使所得超曲面具有c ~ 1或c ~ 2连续。
