varianza poblacional a través de una variables auxiliar en muestreo en dos fases. Algunos …

In this study, we have proposed a new generalized estimator using auxiliary information for
the estimation of population variance in presence and absence of measurement error. The …

This paper contributes to the existing literature on variance estimators by utilizing
supplementary information. The variance estimation problem of a finite population is a …

Yasmeen et al.(Int J Appl Comput Math 1 (2), 1–10, 2015) introduced an exponential ratio
cum dual to ratio type of estimator for the population mean and compared the performance …
