Model‐based estimator of total expenditure on environmental protection
Mathematical Modelling and Analysis, 2007 Expenditure of enterprises on environmental protection has highly positive or zero values. Thus, distribution of such a variable is skewed, and its population variance is high. As a consequence the design‐based estimator of a total expenditure has a high

Approximations to distribution of median in stratified samples
Lietuvos Matematikos Rinkinys, 2011 We consider an Edgeworth type approximation to the distribution function of sample median in the case of stratified samples drawn without replacement. We give explicit expression of this approximation, and also its empirical version based on bootstrap ...

Confidence Intervals in Official Statistics: The Case of Lithuania
Lithuanian Journal of Statistics, 2012 In the paper, the application of confidence intervals in the surveys of official statistics is discussed. It is noticedthat there are situations where at the first sight natural normal distribution-based confidence intervals are not suitable ...

Orthogonal decomposition of finite population L-statistics
Lietuvos 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.

Selection Response in Finite Populations [PDF]
Genetics, 1996 Formulae were derived to predict genetic response under various selection schemes assuming an infinitesimal model. Account was taken of genetic drift, gametic (linkage) disequilibrium (Bulmer effect), inbreeding depression, common environmental variance, and both initial segregating variance within families (σAW02) and mutational (σM2) variance.

Time-Inhomogeneous Finite Birth Processes with Applications in Epidemic Models
Mathematics, 2023 We consider the evolution of a finite population constituted by susceptible and infectious individuals and compare several time-inhomogeneous deterministic models with their stochastic counterpart based on finite birth processes.

Estimation of a quantile in finite population
Lietuvos Matematikos Rinkinys, 2002 An estimator of the quantile of a study variable distribution function in finite population and its confidence interval is proposed. The estimator is adapted to the two-stage cluster sample which is used in a household budget survey carried out in ...

Analysis of samples from finite population
Lietuvos 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].

Evolutionary Dynamics of Coordinated Cooperation
Frontiers 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.

Polygenic Adaptation in a Population of Finite Size
Entropy, 2020 Polygenic adaptation in response to selection on quantitative traits has become an important topic in evolutionary biology. Here we review the recent literature on models of polygenic adaptation.
