Use of an efficient unbiased estimator for finite population mean. [PDF]
PLoS ONE, 2022 In this study, we propose an improved unbiased estimator in estimating the finite population mean using a single auxiliary variable and rank of the auxiliary variable by adopting the Hartley-Ross procedure when some parameters of the auxiliary variable ...

Effects of environmental feedback on species with finite population [PDF]
iScienceSummary: In an unchanging environment, natural selection always selects species with high fitness. In this study, we build a co-evolutionary system to study the interaction between stochasticity in finite populations and environmental feedback.

Estimating finite-population reproductive numbers in heterogeneous populations. [PDF]
J Theor Biol, 2016 The basic reproductive number, R0, is one of the most important epidemiological quantities. R0 provides a threshold for elimination and determines when a disease can spread or when a disease will die out. Classically, R0 is calculated assuming an infinite population of identical hosts.

Spbsampling: An R Package for Spatially Balanced Sampling
Journal of Statistical Software, 2022 The basic idea underpinning the theory of spatially balanced sampling is that units closer to each other provide less information about a target of inference than units farther apart.

Unbiased Estimates for Products of Moments and Cumulants for Finite Populations
Mathematics, 2023 Let FN be the distribution function of a finite real population of size N. Let Fn be the empirical distribution function of a sample of size n drawn from the population without replacement.

Expected mean squares for model effects in the two-way ANOVA model when sampling from finite populations [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2021 The expected mean squares (EMS) for the effects in a two-way ANOVA model are derived when sampling from a finite population, for factors A and B. The A-effects and B-effects are represented by i and j , respectively, in the model.

Evolutionary processes in finite populations [PDF]
Physical Review E, 2013 We consider the evolution of large but finite populations on arbitrary fitness landscapes. We describe the evolutionary process by a Markov, Moran process. We show that to $\mathcal O(1/N)$, the time-averaged fitness is lower for the finite population than it is for the infinite population.
