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.

Abstract:

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.

Key words: INAR(1) model, Bayesian estimate, cumulants, spectral analysis
