Exponential chain dual to ratio and regression type estimators of population mean in two-phase sampling

Abstract

The present work suggests, some estimation procedures of population mean in two phase sampling. Chain-type exponential dual to ratio and regression estimators have been proposed and their properties are explained. Cost aspects of the suggested estimation procedures have been discussed and a recommendation is made to the survey practitioners for their practical applications.
