DOI: 10.24200/sci.2020.53481.3260
Abstract: Several auxiliary information-based estimators of the population variance are available in the existing literature of survey sampling. Mostly, these estimators are based on conventional dispersion measures of the auxiliary variable. In this study, a generalized… read more here.

DOI: 10.3390/math13071063
Abstract: This study explores a unique Finsler space with a Rander’s-type exponential metric, G(α,β)=(α+β)eβ(α+β), where α is a Riemannian metric and β is a 1-form. We analyze the conditions under which its hypersurfaces behave like hyperplanes… read more here.
