正態(tài)模型刻度參數(shù)的經(jīng)驗貝葉斯估計劉榮玄 朱少平(井岡山學(xué)院 數(shù)理學(xué)院 江西 吉安 343009)摘 要:依據(jù)經(jīng)驗貝葉斯估計的思想,研究在平方損失函數(shù)下,正態(tài)模型單參數(shù)的經(jīng)驗貝葉斯(EB)估計問題.先將理論貝葉斯估計用的邊際分布密度函數(shù)及該分布密度函數(shù)的一階導(dǎo)數(shù)表示出來,再利用過去樣本值和當(dāng)前值,采用密度函數(shù)的核估計方法構(gòu)造相應(yīng)的函數(shù),代替理論貝葉斯估計中的函數(shù),得到參數(shù)的經(jīng)驗貝葉斯估計,最后證明了所得到的經(jīng)驗貝葉斯估計是漸近最優(yōu)的.關(guān)鍵詞:正態(tài)模型;參數(shù);經(jīng)驗貝葉斯;估計;漸近最優(yōu)中圖分類號: 文獻標(biāo)識碼:A MR(2000)主題分類號: 62C12,62F12Estimation of the Oneparameter of General Normal Mode by Empirical BayesLIURongxuan Zhushaoping(Jinggangshan College Math and Physic College Jian Jiangxi 343009)Abstract: By means of empirical Bayesian principle and method, a empirical Bayes (EB) estimator of the Oneparameter was discussed under the square loss function for the general normal mode .
