This paper suggests a new family of exponential estimators in the two-phase sampling using
the information of an auxiliary attribute. Theoretically, we obtain the mean square error …

This manuscript proffers a new efficient class of estimators for population mean in two-phase
sampling using the known population proportion. The usual mean estimator, classical ratio …

Transformation techniques have been used to increase the efficiency of estimators in
sample surveys. In this paper, some classes of population mean estimators using …

A family of exponential-type estimator for estimating population mean in two-phase sampling
when the population proportion of the auxiliary character is available is proposed in this …

This paper presents an efficient class of estimators for estimating the population mean of the
variate under study in two-phase sampling using information on several auxiliary variates …

This paper presents exponential-type ratio and product estimators for a finite population
mean in double sampling using information on several auxiliary variates. The proposed …

This paper considers a chain ratio-cum-dual to ratio type estimator for estimating population
mean of the study variate using two auxiliary variates under double (two-phase) sampling …

population mean of the study variable by using the information on an auxiliary attribute …

In this article, an efficient class of estimators of population mean is opined under double
sampling scheme using auxiliary information which admits various existing estimators like …

Bahl and Tuteja (1991) have given exponential estimator to estimate population mean.
