COMPARISON OF SOME STATISTICAL EXPERIMENTS ASSOCIATEDWITH SAMPLING PLANS
Abstract: Some experiments occurring in sampling theory may be described as
Consider a finite population and a characteristic of interest which, with varying
amount (value, degree, etc.), is possessed by all individuals in . Let be the amount of
this characteristic for an individual .
It is known that belongs to some set of functions on .
Let be a sampling plan, i.e. a probability distribution on the set of finite sequences of
elements from . If this sampling plan is used and if the characteristics of sampled
individuals are determined without error, then the outcome
obtained with probability
Let denote the experiment obtained by observing and assume that is not too
small. Then is at least as informative as if and only if the sampled subset under
is ”stochastically contained” in the sampled subset under Using the theory of
comparison of statistical experiments we shall here discuss this and other related
