针对传统断面交通流速度分布假设关系较片面、回归数据不全面和拟合模型不具有普遍性和精确性等问题，本文采用二分K-FCM结合算法对连续收集的大样本交通流数据中速度、交通量和占有率三者进行聚类划分，再利用自主建立的MLE-LM算法拟合运行车速三参数Weibull分布，并将其拟合结果与正态分布和高斯多峰拟合结果对比.该算法模型收敛快，拟合结果精度高，不易收敛于局部极值，且对样本容量的适应能力强.研究结果表...

On the Existence of the MLE for a Directed Random Graph Network Model with Reciprocation
Algebraic statistics Dyadic independence Exponential random graph model
2010/10/14
Holland and Leinhardt (1981) proposed a directed random graph model, the p1 model, to describe dyadic interactions in a social network. In previous work (Petrovic et al., 2010), we studied the algebra...

截尾寿命试验中参数的 MLE 的收敛速度
收敛速度 参数 截尾寿命
2009/9/18
本文所考虑的截尾寿命试验是一种包含定时和定数截尾的混合型寿命试验。它的做法是从总体中随机抽取 n 个个体,同时进行寿命试验。如果在时刻 T 之前观察到 r_n 个个体“寿终”,则试验就在第 r_n 个寿终的时刻停止,否则就进行到时刻 T 为止。确切地,设 n个样品的寿命为 X_1(ω),X_2(ω),…,X_n(ω),它们均取值于(0,∞),为样本空间(\Omega,\mathcal{F},P_...
