摘要:

利用矩方法和Bayes方法研究INGARCH(1,1)模型的参数估计问题, 证明了矩估计量的强相合性和渐近正态性. 模拟结果表明, 两种估计量都得到了较好的结果.

关键词: 渐近性, Bayes推断, INGARCH(1,1)模型, 矩估计量

Abstract:

Using methods of moment and Bayes, the authors considered the problem of parameter estimation in the INGARCH(1,1) model. Strong consistency and asymptotic normality of the moment estimator were proved. The simulation study shows that both estimators perform well.

Key words: asymptotics, Bayesian inference, INGARCH(1,1) model, moment estimator
