摘要
研究简单回归模型中响应变量受到另一随机变量序列污染时,模型参数和污染系数的估计,运用EM算法给出了两类污染数据回归模型的参数的极大似然估计(MLE),并用Gibbs抽样的方法给出了未知参数的Monte-Carlo估计.
In this paper the estimation of the parameters and coefficient of contamination for the simple regression model are studied when its response variables are contaminated by another random variable sequence.We obtain the MLE evaluations of two contaminated regression model parameters using EM algorithm.And using Gibbs sampling we also get the parameters'Monte-Carlo evaluations.
