Description:
The sampling theory developed and decribed by Pierre Gy is compared to design-based classical finite sampling methods for estimation of a ratio of random variables. For samples of materials that can be completely enumerated, the methods are asymptotically equivalent. Gy extends the finite sampling methods to situations in which complete enumeration of samples is not feasible. Gy's methods involve a set of sampling constants related to the heterogeneity of the material sampled; methods to estimate these constants from grouped data are given. Computer programs for the estimation of these constants are described, and environmental applications are discussed.
