In order to control the influence of some outstanding points to surface fitting, a robust fitting of the trend surface by using an equivalent weight is adopted. 在趋势面拟合过程中,提出将局部有显著起伏的采样点视为异常观测值,采用抗差估计法,控制显著异常点对曲面拟合的不利影响;
Objective : To determine whether the magnitude of the change of the incretin levels and effect is greater after GBP compared to a low caloric diet, after equivalent weight loss. 研究目标:此项研究的目的是确定达到同样的减肥效果胃旁路手术所致肠促胰岛素水平的变化以及影响与低热量饮食相比是否更显著。
This paper also discusses the calculation model and the construction method of single equivalent weight torsional vibrating system. 主要讨论了机床进给传动链中,单支当量扭转振动系统的计算模型及其建立方法。
This paper compares and analyses the robustness of two kinds equivalent weight functions with a few examples. 本文利用两类不同观测值的几个算例,对两种等价权函数的抗差效果进行了比较分析。
Critical values of the equivalent weight function are often fixed in constants in robust estimation. 抗差估计等价权函数中临界值一般定为常数。
