The volunteer’s dilemma in finite populations [PDF]

open access: yesJournal of Evolutionary Economics, 2021
AbstractWe study the long-run stochastic stability properties of volunteering strategies in finite populations. We allow for mixed strategies, characterized by the probability that a player may not volunteer. A pairwise comparison of evolutionary strategies shows that the strategy with a lower probability of volunteering is advantaged.

Evolutionary processes in finite populations [PDF]

open access: yesPhysical 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.

Estimation of a Ratio in the Finite Population [PDF]

open access: yesInformatica, 2005
Summary: Estimation of the ratio of two totals is considered, when a probability sample from the finite population is available. Four estimators of the ratio are examined. The first one -- called ``simple'' -- is the ratio of the Horvitz-Thompson estimators of totals; the second -- the ratio of two ratio estimators of totals; the third one -- the ratio

LETHALS IN FINITE POPULATIONS [PDF]

open access: yesEvolution, 2002
It has been assumed, based on theoretical studies, that lethals with the level of dominance estimated from experimental studies would have an allele frequency that is virtually independent of effective population size. However, here it is shown numerically that the expected frequency of lethals with low levels of dominance is also dependent on finite ...

Dynamic Properties of Evolutionary Multi-player Games in Finite Populations

open access: yesGames, 2013
William D. Hamilton famously stated that “human life is a many person game and not just a disjoined collection of two person games”. However, most of the theoretical results in evolutionary game theory have been developed for two player games.

Orthogonal decomposition of finite population L-statistics

open access: yesLietuvos Matematikos Rinkinys, 2009
In this paper we study orthogonal decomposition of finite population L-statistics. We propose quite simple form of first two terms of such decomposition.

Analysis of samples from finite population

open access: yesLietuvos Matematikos Rinkinys, 2008
This paper deals with asymptotic properties of probabilitydistributionsof sample statistics when samples are selected from finite populations.These properties also were analysed by P. Erdos, A. Rényi [3] and J. Hájek [4].

Generalized Estimator of Finite population Variance [PDF]

open access: yesJournal of Statistical Theory and Applications (JSTA), 2015
In this paper a generalized class of finite population variance is suggested and its large sample bias and mean square error are derived. Further some special cases of this class are considered along with a numerical example to compute and compare their ...

Finding the Size of a Finite Population [PDF]

open access: yesThe Annals of Mathematical Statistics, 1967
There are fixed sample size methods for estimating the unknown size N of a finite population by tagging the elements of a first sample and then counting the number of tagged elements of a second sample [1, p. 43]. Less well known are sequential methods [2], which have the advantage that the total sample size automatically adjusts itself to the unknown ...

Evolutionary Dynamics of Coordinated Cooperation

open access: yesFrontiers in Ecology and Evolution, 2018
In social evolution theory, unconditional cooperation has been seen as an evolutionarily unsuccessful strategy unless there is a mechanism that promotes positive assortment between like individuals.
