Sample rotation theory with missing data
This paper studies how the sample rotation method is applied to the case where item non-response occurs in surveys. The two cases where the response to the first occasion is complete or incompleteExpand

Admissible estimation of linear functions of characteristic values of a finite population
The problem on admissibility of estimators is considered based on the point of view of the superpopulation model. The necessary and sufficient conditions for linear estimators of an arbitrary linearExpand

Objective To analyze and summarize the risk factors of radial artery spasm in patients with acute myocardial infarction treated by radial artery interventional therapy. Methods From AugustExpand
The design and data processing of the Sampling Survey of Children's situation in China, 1987
In July of 1987, the Sampling Survey of Children's Situation was conducted in 9 provinces/autonomous regions of China. A stratified two-stage cluster sampling plan was designed for the survey. TheExpand
Fractal Growth and Form by Molecular Dynamics
The fractal growth and form is considered by molecular dynamics and simulated using computer.
Edge Node Data Classification Method For Power Internet Of Things
Under the background of electric power Internet of things (P-IoT), the traditional cloud computing operation mode with centralized processing of data center is difficult to adapt to the rapidExpand
A new method for increasing precision in survey sampling
Abstract This paper proposes a new method for increasing the precision in survey sampling, i.e., a method combining sampling with prediction. The two cases where auxiliary information is or notExpand
An Adaptive Coincidence Feeder Automation Method Considering the Processing of Single Phase to Ground Fault
TLDR
In view of the problems existing in the current feeder automation (FA), such as over reliance on communication, difficulty in security protection, and self adaptation of fixed value parameters, etc, an adaptive coincidence FA method is proposed in this paper considering the processing of single phase to ground fault.
