摘要 结合m相依随机变量和WOD随机变量的概念,给出m-WOD随机变量的概念,它包含了NA随机变量,m-NA随机变量,NSD随机变量,NOD随机变量,END随机变量,m-END随机变量,WOD随机变量等负相依随机变量.基于误差为m-WOD随机变量,我们研究非线性回归模型参数最小二乘(LS)估计,获得了参数LS估计的概率不等式.作为应用,在不同的矩条件下,获得LS估计的完全收敛速度和依概率收敛速度,推广了已有文献的结果. Combining the conception of m dependent random variables with WOD random variables, the conception of m-WOD random variables is given in this paper, which contains many negative dependent random variables such as NA, m-NA, NSD, NOD, END, m-END and WOD. Based on the m-WOD errors, the least squares (LS) estimator of nonlinear regression models is investigated and some probability inequalities for the LS estimator are obtained. As an application, the complete convergence and convergence in probability are presented under di?erent moment conditions, which generalize the corresponding results.
