Abstract
Jackknife study was conducted along two different perspectives:(1) applied to reduce bias;(2) applied to variance estimation.This paper discussed variance estimator based on the jackknife in PPS sampling,and got a conclusion that E{v(^/θ)} equal to the unbiased estimate of variance.
A significance statement is not available in the OpenAlex record.
A contribution statement is not available in the OpenAlex record.
Method details are not available in the OpenAlex metadata.
Findings are not separately available in the OpenAlex metadata.
Limitations are not available in the OpenAlex metadata.
Application details are not available in the OpenAlex metadata.
