联邦福利质量控制项目中的回归估计AI 解读

States that administer federal family welfare programs review samples of the beneficiaries to guide corrective actions. Federal agencies review subsamples of the state samples to compute overpayment error rates using a regression estimator. These federal estimates make state-to-state comparisons of quality possible and are also used for fiscal sanctions. Such applications of the regression estimator have been widely challenged. We show that the regression estimates and…

样本调查中模型依赖推断与概率抽样推断的评估AI 解读

In this paper we are concerned with inferences from a sample survey to a finite population. We contrast inferences that are dependent on an assumed model with inferences based on the randomization induced by the sample selection plan. Randomization consistency for finite population estimators is defined and adopted as a requirement of probability sampling. A numerical example is examined to illustrate the dangers in the use of model-dependent estimators even when the model…

美国人口普查局当前人口调查的重新设计AI 解读

In February 1954 a redesign of the Current Population Survey was introduced that provided for a more efficient system of field organization and supervision as well as some advances in methods. The sample is now spread over 230 areas instead of 68 areas with the same number of households as heretofore. A composite estimation procedure has been introduced which reduces the sampling variability for most estimates. Also, there has been a considerable reduction in the variance of…
