題名: | Approximate confidence sets for a stationary AR process | 作者: | 翁久幸;Michael Woodroofe | 關鍵詞: | Asymptotic expansions;Asymptotic confidence levels;Stationary autoregressive process;Very weak expansions | 日期: | May-2004 | 上傳時間: | 19-Dec-2008 | 摘要: | Approximate confidence intervals are derived for the autoregressive parameters of a stationary, Gaussian auto-regressive process of arbitrary order and shown to be asymptotically correct to order o(1/n), where n is the sample size. Simulation studies are included for small and moderate sample sizes for the case of two auto-regressive parameters, and these indicate excellent approximation for sample sizes as small as n = 10,20. The convergence is in the very weak sense, and the derivation differs from most existing work through its direct focus on Studentized estimation error and its use of Stein’s identity. | 關聯: | Journal of Statistical Planning and Inference, 136, 2719-2745 | 資料類型: | article | DOI: | http://dx.doi.org/10.1016/j.jspi.2004.11.007 |
