This paper establishes the robust estimates of parameter vector and variance factor with minimum mean square error, all parameters of which are determined according to statistics. 本文就合适于测量数据处理的污染误差模型,提出了未知参数向量和方差的最小均方误差的抗差估计,探讨了最小均方误差估计的计算问题。
Solution of unit weight variance factor in l_p, estimation Lp估计中单位权方差因子(VF)的求解
According to the exist experiment data, we taking advantage of classical kinetics equation and using the least-squares fitting, get RDX thermal decomposition temperature and time functional equation, and deduce activation energy and variance factor and reaction mechanism function. 根据已有的实验数据,利用经典的唯象动力学方程,采用最小二乘法线性拟合,得出黑索今热分解温度和时间的关系式,推导出其表观活化能、表观指前因子及反应机理函数。
