不均等选择概率下的加权调整研究
发布时间：2019-04-01 15:21
【摘要】：从不均等选择概率的角度,提出两类常见的权数调整类型及其调整方法:一是规模调整,使得样本单元权数之和等于总体规模;二是结构调整,使得样本结构和总体结构一致,并构造出加权调整的设计效应模型,应用于复杂样本设计。案例分析显示,加权调整往往导致设计效应变大,带来负的效应,但校准调整能降低设计效应,提高估计精度。
[Abstract]:From the point of probability of unequal selection, two kinds of weight adjustment types and their adjustment methods are put forward: first, the size adjustment makes the sum of the weights of sample units equal to the overall size; The second is structural adjustment, which makes the sample structure and the overall structure consistent, and constructs a design effect model of weighted adjustment, which is applied to complex sample design. Case analysis shows that weighted adjustment often leads to large design effect and negative effect, but calibration adjustment can reduce design effect and improve estimation accuracy.
