Two-Stage Adaptive Cluster Sampling
Biometrics, 1997Summary: Adaptive cluster sampling is a powerful method for parameter estimation when a population is highly clumped with clumps widely separated. Unfortunately, its use has been somewhat limited until now because of the lack of a suitable theory for using a pilot survey to design an experiment with a given efficiency or expected cost.

Adaptive Cluster Sampling in Two-stage Sampling
Australian & New Zealand Journal of Statistics, 2014Summary: 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.

Two-Stage Adaptive Cluster Sampling
2021Adaptive sampling is a method in which selection of units at any stage of sampling depends upon the information collected from the already selected units in the initial sample. It means, if one finds what he/she is looking for at a particular location then he/she would sample in the vicinity of that location with the hope of obtaining more information.

Two-Stage Inverse Adaptive Cluster Sampling
2021It is well known that if the population under study is homogeneous then one can assign equal probability of selection to the units in the population and can estimate the population parameters using the selected sample. But if the population has clumps in it then the equiprobable assignment may lead to poor estimates of the population parameters.

Double Sampling for Cluster- or Two-Stage Sampling
International Statistical Review / Revue Internationale de Statistique, 1972Survey sampling literature describes several methods of using certain auxiliary information to attain more efficient sampling and estimation procedures. If the required information is not available in advance for the entire population, it might be advantageous to collect certain items for a larger, preliminary sample and then use this to improve on the

Two-Stage Cluster Sampling for Pine Tip Moths
Environmental Entomology, 1983Techniques are discussed for sampling immature stages of pine tip moths, Rhyacionia spp. (Lepidoptera: Tortricidae, Olethreutinae), on young trees. Sampling is described for all immature stages of the Nantucket pine tip moth, R. frustrana (Comstock), and the pitch pine tip moth, R. rigidana (Fernald), on 3-year-old loblolly pine, Pinus taeda L., in the

Theory and Methods: Hypothesis Testing in Two‐Stage Cluster Sampling
Australian & New Zealand Journal of Statistics, 1998Correlated observations often arise in complex sampling schemes such as two‐stage cluster sampling. The resulting observations from this sampling scheme usually exhibit certain positive intracluster correlation, as a result of which the standard statistical procedures for testing hypotheses concerning linear combinations of the parameters may lack some

On the Use of Two‐stage Cluster Samples in Epidemiological Population Studies
Biometrical Journal, 1988AbstractThis paper discusses the need to account for the sampling scheme in an analysis of epidemiological population data which were collected by a two‐stage cluster sample. An example is presented where for validity reasons one should generally account for the sampling scheme, though a rule‐of‐thumb is given to estimate the effect of not doing so ...
