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 ...
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 ...

Example 1: 2-Stage Systematic Sampling Suppose that both the initial Markov chain sample and any secondary samples are single random start systematic samples. Then the transition probability matrices, P and Q, are the identity matrices. In addition, s fR1; n R1; . . . ; H ...
The transect sampling actually is a two-stage sampling. In the first stage, PSUs are selected ran- domly on a 4km脳4km area frame. In the second stage, the selected PSUs are sampled only along the roadwithin PSUs, called transect line.The samplingworks inthe field are totake pictures...
1) two-stage cluster sampling 二阶段整群抽样1. Firstly, we give an effective sampling design: a simple random case sample with replacement is drawn out of all cases; the control sample is drawn out of all controls with two-stage cluster sampling. 首先,我们设计了一个有效的抽样方案:采取...
