Modeling spatial aggregation of finite populations

Ecology, 2010
Accurate description of spatial distribution of species is essential for correctly modeling macroecological patterns and thus to infer mechanisms of species coexistence. The Poisson and negative binomial distribution (NBD) are most widely used to respectively model random and aggregated distributions of species in infinitely large areas.

Analysis of a Genetic Model with Finite Populations

2005
Simple genetic algorithms on populations of l-binary words usually become iterative systems on 2l dimensional spaces when populations have size infinite. However, in a particular model (BCCG model) previously introduced, it has been shown that the iterative system works in a l-dimensional space.

Modeling Finite Populations.

2003
It is common to model the dynamics of an evolutionary algorithm by considering a typical or representative population. We consider modelling a genetic algorithm using two different descriptions of this typical population. The first using cumulants describing the distribution of fitnesses, the second using the distribution itself.

Estimation of the Finite Population Covariance

2007
Some calibrated estimators of the finite population covariance are presented. The estimators are constructed using different calibration equations and different loss functions. In the most cases the explicit solution of the calibration problem does not exist. The approximate iterative equations for the calibrated weights can be derived.

Finite Population Sampling

2014
It is fair to say that most of the information we know about contemporary society is obtained as the result of sample surveys. Real populations are finite and the branch of statistics which treats sampling of such populations is called survey sampling. For many years survey sampling remained the province of “survey samplers” with very little input from
