RANDOM SAMPLING AND THE RATE OF GENE REPLACEMENT [PDF]
Evolution, 1967 The time required, under a deterministic treatment, for a given change in gene frequencies brought about by the action of natural selection has been known since the classical papers by Haldane in the 1920's (for a summary see Haldane, 1932). Being deterministic, this treatment takes no account of "random sampling" changes in gene frequency due to the ...

Limit laws for a class of diminishing urn models. [PDF]
Discrete Mathematics & Theoretical Computer Science, 2007 In this work we analyze a class of diminishing 2×2 Pólya-Eggenberger urn models with ball replacement matrix M given by $M= \binom{ -a \,0}{c -d}, a,d∈\mathbb{N}$ and $c∈\mathbb{N} _0$.

An Unbiased Estimator of Finite Population Mean Using Auxiliary Information
Journal of Statistical Theory and Applications (JSTA), 2021 In this paper, an unbiased estimator is constructed by using a linear combination of an estimator of study variable and mean per unit estimator of an auxiliary variable under simple random sampling without replacement scheme.

On the implementation of maximum entropy sampling with unequal probabilities and without replacement
MethodsXSampling with maximum entropy offers robustness to statistical inference based on randomization theory. However, there were no comprehensive, practical guides explaining how to implement maximum entropy sampling for finite populations with unequal ...

Error Analysis by Replaced Samples
Journal of the Royal Statistical Society Series B: Statistical Methodology, 1971 Summary For normal observations {Xi, j = 1, …, N}, certain weighted sums Yi, are used to draw inferences about the sum Y of a further N observations. The same family of weights {Wij} are applied in error analysis of general computations t on general samples x1, …, xN, with approximate validity in a wide range of situations.

On a Scheme of Sampling of Two Units With Inclusion With Inclusion
Austrian Journal of Statistics, 2016 This paper introduces an unequal probability sampling without replacement scheme with inclusion probability proportional to size. This new scheme possesses some desirable properties with regard to ?i and ?ij , and provides a non-negative variance ...
