The quality of inferences made from geostatistical data is affected significantly by the spatial locations, or design, of the sites that are sampled. A large body of published work exists on sampling ...

Cohort sampling designs are proposed which one would intuitively expect to be more efficient than nested case-control sampling. Two of these designs start with a nested case-control sample and ...

The specific monitoring design (the choice of location and timing of sample collection) that best meets project objectives will depend on the type and scale of the project and the degree to which ...

Sampling design is of primary importance for empirical studies, in particular, population genetics. For parasitic organisms, a rather frequent way of sampling individuals from local populations is to ...

This example illustrates the use of regression analysis in a simple random cluster sampling design. The data are from S rndal, Swenson, and Wretman (1992, p. 652). A total of 284 Swedish ...

If no other sources are available to measure certain variables of a target population, Statistics Netherlands often uses a random sample, i.e. a sample of units from the population drawn in accordance ...

With this approach, a second site (a baseline reference site) in a very similar watershed is monitored. Changes in the BMP site are compared to this baseline. The monitoring approach is greatly ...

Survey research is an important form of scientific inquiry1 that merits rigorous design and analysis.2 The aim of a survey is to gather reliable and unbiased data from a representative sample of ...
