A new population mean estimator under non-response cases
Journal of Taibah University for Science, 2022 Using the information in x, we consider a new estimator that uses an exponential function to estimate the unknown population mean of y in the case of non-responding units. These cases are divided into two categories as Case I and Case II.

Advances in Estimation of Sensitive Issues on Successive Occasions
Statistica, 2020 Surveys related to sensitive issues are accompanied with social desirability response bias which flaw the validity of analysis. This problem became serious when sensitive issues are estimated on successive occasions.

Generalized Neutrosophic Sampling Strategy for Elevated estimation of Population Mean [PDF]
Neutrosophic Sets and Systems, 2023 One of the disadvantages of the point estimate in survey sampling is that it fluctuates from sample to sample due to sampling error, as the estimator only provides a point value for the parameter under discussion.

An improved family of estimators for estimating population mean using a transformed auxiliary variable under double sampling [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2023 The performance of a population mean estimator can be improved by transformation techniques using a subset of the population data. An improved family of estimators for population mean has been proposed under double sampling using a transformed ...

On Influencing Population Means
Epidemiology, 2012 Findings on the existence or the lack of temporal trends in sperm concentration at the population level have been used to discuss the role of environmental factors (including endocrine disruptors) on male fertility. An assumption sometimes made 1 is that temporal trends in biological parameters such as sperm concentration will parallel temporal trends ...

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.

Migration as a means of population control [PDF]
Population Studies, 1971 Abstract The more crowded West Indian islands lose citizens each year through emigration, and they are small enough for an appreciable relief of population pressure to be thereby afforded. Each year some of the inhabitants of Java move to Sumatra and elsewhere under official sponsorship, part of the rationale for the policy being the relief of ...

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.
