摘要
借助Cochran(1977)提出的的计量误差数学模型 ,分析了计量误差的来源及其对总误差的影响 ,指出了农产量抽样调查中计量误差的四种来源分别为设计缺陷、调查员效应、被调查者问题、任务特性 ,并以甄别调查员效应为例 ,对已取得的调查数据中可能存在的计量误差 ,运用效应比较甄别法和贝叶斯估计 3σ图甄别法进行了实证演示。
The mathematical model of Errors of Measurement (EOM) advanced by Cochran in 1977 is applied to analyze the origin of EOM and its impact on total errors in Corn Yield Sample Surveys. It shows that there are four kinds of origins of EOM. To demonstrate the effect of investigator to EOM, two kinds of methods are used in the empirical study for the screening of EOM in ex post survey data: screening method of effect comparison and Bayesian method for screening.
