摘要 利用Bayes方法研究INAR(1)模型的参数估计,给出了模型参数的Bayes估计因子,并通过数值模拟将Bayes估计与Yule-Walker估计、条件最小二乘估计、条件极大似然估计进行比较.结果表明,Bayes估计方法在一定情形下优于其他方法. We studied the parameter estiamtion for the INAR (1) model by Bayes method, compared the Bayes estiamtor with Yule-Walker estimator, the conditional least squares estimator, and the maximum likelihood estimator via simulation. The simulation results state that Bayes estimator is better than others in some situation.
