New Chain Estimators for Finite Population Mean Under Stratified Two-Phase Sampling

Housila P. Singh, Pragati Nigam

Abstract



In this paper, for estimating the population mean (PM) we have propounded some chain ratio-product-type (RPT) estimators and chain ratio-product-type exponential (RPTE) estimators along with their generalized versions. Properties of the developed estimators are studied up to first order of approximation (foa). Comparisons are also made among all the considered estimators. To support the present research work, an empirical study is also performed.

Keywords


Bias, Mean Squared Error (MSE), Auxiliary Variable (AV), Study Variable (SV), Stratified two Phase Sampling.
