A simple random sample is a subset of a statistical population where each member of the population is equally likely to be chosen.

Using pooled samples to characterize populations is not only more cost-efficient, but also in some cases it can lead to more precise and less biased parameter estimation than that occurs with ...

A single sample of individuals from the population, those on list K, together with the identification of the list on which they last appeared prior to list K is obtained. Under relatively weak ...

We develop a Bayesian approach to sample size computations for surveys designed to provide evidence of freedom from a disease or from an infectious agent. A population is considered "disease-free" ...
