抽样调查缺失值插补的贝叶斯程序
A new method is proposed for imputation of missing values in sample survey data. The procedure uses standard statistical methodology, permits a general specification of the nonresponse process, and does not impose specific model assumptions. Prior information from past similar surveys or from other sources may be incorporated in a routine manner.
带顺序约束的分类数据模型中有限总体参数的贝叶斯估计
SUMMARY This note describes a Bayesian method for estimation of finite population parameters in general population surveys where acceptable regression-type models are typically unavailable. A categorical data model is adopted as in Ericson (1969, Section 4). However, specifications of smoothness are incorporated into the prior distribution. These smoothness conditions are expressed as unimodal or, possibly, multi-modal order relations among the category probabilities.…
