Two-Stage Negative Adaptive Cluster Sampling

Communications in Mathematics and Statistics, 2018
The authors deal with adaptive cluster sampling, a better alternative of the simple random sampling in cases when the population is rare and clustered. With this approach, auxiliary information is often used in order to overcome the problem with the increasing sample size.

Ratio estimators in adaptive cluster sampling

Environmetrics, 2007
AbstractIn most surveys data are collected on many items rather than just the one variable of primary interest. Making the most use of the information collected is a issue of both practical and theoretical interest. Ratio estimates for the population mean or total are often more efficient.

Adaptive Cluster Sampling

2021
While conducting a sample survey, a number of difficult sampling problems are encountered. One of them is the problem in estimating the population mean/total when it is rare or geographically uneven. If the population of interest is hidden or elusive, then it becomes difficult to identify it for sampling.

Application of adaptive sampling in fishery part 2: Truncated adaptive cluster sampling designs [PDF]

, 2001
There are some experiences that researcher come across quite number of time for very large networks in the initial samples such that they cannot finish the sampling procedure. Two solutions have been proposed and used by marine biologists which we discuss in this article: i) Adaptive cluster sampling based on order statistics with a stopping rule, ii ...

Inverse Adaptive Cluster Sampling

Biometrics, 2001
Consider a population in which the variable of interest tends to be at or near zero for many of the population units but a subgroup exhibits values distinctly different from zero. Such a population can be described as rare in the sense that the proportion of elements having nonzero values is very small.

Negative adaptive cluster sampling

Model Assisted Statistics and Applications, 2019
The traditional sampling methods such as simple random sampling, stratified sampling etc. cannot be used to study the rare and clustered populations. Such type of populations are frequently observed in ecological, environmental and social sciences. In such situations, often the auxiliary information is collected along with the variable of interest ...

Inverse Adaptive Cluster Sampling

2021
When the population under study is homogeneous with respect to the characteristic of interest then the traditional method such as SRSWR/SRSWOR can be used to estimate the population parameters. But if the population under study is rare and clustered then the use of these sampling methods may lead to poor estimates of the population parameters.

Adaptive Cluster Sampling in Two-stage Sampling

Australian & New Zealand Journal of Statistics, 2014
Summary: Adaptive cluster sampling can be a useful design for surveying rare and clustered populations. Here we present a new development in adaptive cluster sampling where we use a two-stage design and extend the complete allocation sampling method.

Adaptive Cluster Double Sampling

2021
ACS introduced by Thompson (1990) has been found appropriate for sampling of rare and clustered populations. But it suffers from drawback of losing control of the final sample size. There have been several suggestions for limiting this final sample size of adaptive cluster samples.
