2) multiple-stage cluster sampling 多阶段整群抽样 3) multi-stage cluster random sampling 多阶段整群随机抽样 1. It was a descriptive epidemiologic study,usingmulti-stage cluster random sampling. 研究采用描述性流行病学的方法,通过多阶段整群随机抽样,从拱墅区中先抽取康桥镇作为一级抽样单元,再从康桥镇...
Example of Two-Stage Cluster Sampling A garment manufacturer has N = 90 plants located throughout the United States and wants to estimate the average number of hours that the sewing machines were down for repairs in the past months. Because the plants are widely scattered, she decides to ...
The samples from each cluster are combined into a single estimate of the population mean and variance. 17 June, 2003 Sampling Two-stage Proportionate to size (PPS) Cluster Sample with Quota Sampling in the Second Stage: The population is divided into multiple clusters. Stage I: A random ...

two-stage samplingunbiased estimatorIn surveys of natural resources in agriculture, ecology, fisheries, forestry, environmental management, etc., cost-effective sampling methods are of major concern. In this paper, we propose a two-stage cluster sampling (TSCS) in integration with the hybrid ranked ...
Two-stage NACSRegression estimatorIf the population is rare and clustered, then simple random sampling gives a poor estimate of the population total. For such type of populations, adaptive cluster sampling is useful. But it loses control on the final sample size. Hence, the cost of sampling ...
Here we present a new development in adaptive cluster sampling where we use a two‐stage design and extend the complete allocation sampling method. In the proposed new design the primary sample units are selected and, depending on the value of a preset condition, the entire primary unit is ...
Two-stage cluster samplingVariance estimationVariance estimation in the presence of imputed data has been widely studied in the literature. It is well known that treating the imputed values as if they were true values could lead to serious underestimation of the true variance, especially if the ...

Local Polynomial Regression Estimation In Two-Stage Sampling We consider local polynomial regression estimation for finite population totals in two-stage element sampling. The estimators are linear combinations of estimators of cluster totals with weights that are calibrated to known control total... JY ...
