Abstract

The present paper focuses on the study of combined-type family of estimators of population mean in stratified random sampling in the presence of non-response. In this paper, we have suggested a family of factor-type estimators of population mean in stratified random sampling under non-response using an auxiliary variable. The properties of the family have been discussed in detail. The theoretical results are also supported by an empirical study.
