本文针对属性特征的KUK模型建立了贝叶斯估计理论,求出了在先验分布是混合贝塔先验分布、抽样方法是简单随机抽样情况下总体敏感特征比例的贝叶斯估计,并且使用后验均方误差作为精度标准,对贝叶斯估计与极大似然估计进行比较。
本文針對屬性特徵的KUK模型建立瞭貝葉斯估計理論,求齣瞭在先驗分佈是混閤貝塔先驗分佈、抽樣方法是簡單隨機抽樣情況下總體敏感特徵比例的貝葉斯估計,併且使用後驗均方誤差作為精度標準,對貝葉斯估計與極大似然估計進行比較。

In this paper ,we have established the Bayesian estimation theory for the qualitative characteristics randomized response model proposed by Kuk (1990) .We obtained the Bayesian estima-tion of population proportion of a sensitive characteristic as prior information is mixture of Beta distri-butions and sampling method is simple random sampling .And to compare Bayesian estimation to classi-cal maximum likelihood estimation by means of posterior mean square error as the precision measure .
