改进小区域人口估计程序的评价AI 解读

"We provide and illustrate methods for evaluating across-the-board ratio estimation and synthetic estimation, two techniques that might be used for improving population estimates for small areas. The methods emphasize determination of a break-even accuracy of knowledge concerning externally obtained population totals, which marks the point at which improvement occurs." The techniques are illustrated using 1980 U.S. census data.

系统抽样中若干方差估计量的考察AI 解读

This article provides to the survey practitioner some guidance about the problem of variance estimation for equal probability single-start systematic samples. An investigation of eight alternative estimators of the variance of the sample mean is presented. In the first half of the investigation, the theoretical properties of the estimators are compared using several superpopulation models; in the second half, the comparison is empirical, based on several real populations.…

非线性变量测量误差模型的估计AI 解读

An estimation procedure is presented for the coefficients of the nonlinear functional relation, where observations are subject to measurement error. The distributional properties of the estimators are derived, and a consistent estimator of the covariance matrix is given. In deriving the results it is assumed that the covariance matrix of the observational errors is known and that this covariance matrix is $o(n^{-1/3})$, where $n$ is the index of the sequence of estimators.

二次变量测量误差模型的估计AI 解读

An estimator is presented for the coefficients of the quadratic functional relationship. The estimator is shown to be asymptotically normally distributed as the sample size increases. In deriving this result it is not assumed that replication occurs. A Monte Carlo study is presented agreeing well with the asymptotic results. An example from the earth sciences is analysed.

有限总体中的复合估计AI 解读

It is common practice in large recurring surveys to employ rotation sampling schemes. Composite estimators are often used in association with rotation schemes to reduce the variability of the survey estimators. In this article, expressions for the variances of certain composite estimators are derived. It is demonstrated how the variance expressions may be used in planning panel surveys and in certain time series analyses. This work is illustrated by the Census Bureau's…
