Improved neutrosophic exponential-ratio estimator of population mean with simple random sampling [PDF]
Neutrosophic Sets and SystemsIn this paper we present a neutrosophic exponential-ratio estimator for calculating the population mean using simple random sampling. In sampling methods classical statistics always depends on exact and complete data, but when we are dealing with unclear

Comparison of lognormal population means [PDF]
Proceedings of the American Mathematical Society, 1994 Comparisons of two lognormal population means are investigated. For large samples, the conventional test for significance of the population means is the ordinary Student t-test with normal critical value. By Chen and Loh’s result (Ann. Statist. 20 (1992)), however, the transformed t-test based on log-data is asymptotically more powerful than the ...

Ratio Estimators in Simple Random Sampling Using Information on Auxiliary Attribute [PDF]
, 2008 Some ratio estimators for estimating the population mean of the variable under study, which make use of information regarding the population proportion possessing certain attribute, are proposed.

Parametric modelling of cost data: some simulation evidence [PDF]
, 2005 Recently, commentators have suggested that the distributional form of cost data should be explicitly modelled to gain efficiency in estimating the population mean.

Two Populations Mean-Field Monomer–Dimer Model [PDF]
Journal of Statistical Physics, 2018 A two populations mean-field monomer-dimer model including both hard-core and attractive interactions between dimers is considered. The pressure density in the thermodynamic limit is proved to satisfy a three-dimensional variational principle. A detailed analysis is made in the limit in which one population is much smaller than the other and a ...

Dynamical Mean Field approximation of a canonical cortical model for studying inter-population synchrony [PDF]
, 2011 The goal of this paper is twofold. We propose and explore a model to study the synchronization among populations in the canonical model of the neocortex proposed previously by (R.J. Douglas, K.A.C. Martin, A functional microcircuit for cat visual cortex.

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.

Application of Randomized Response Techniques Using Dichotomous Response for Mean Wage in Czechia and Slovakia [PDF]
Statistika: Statistics and Economy JournalResearch of controversial topics (drug consumption, corruption) requires reliable estimates of population means of sensitive variables (spending on drugs, illegal sources of income). To avoid non-response and fabricated responses surveys using randomized

Pushed beyond the brink: Allee effects, environmental stochasticity, and extinction [PDF]
, 2014 A demographic Allee effect occurs when individual fitness, at low densities, increases with population density. Coupled with environmental fluctuations in demographic rates, Allee effects can have subtle effects on population persistence and extinction ...

Predictive Estimation of Finite Population Mean Using Exponential Estimators [PDF]
Statistika: Statistics and Economy Journal, 2014 This paper suggested the ratio-type and product-type exponential estimators of the population mean of a study variable through predictive approach using Bahl and Tuteja (1991) ratio-type and product-type exponential estimators as a predictor of the mean
