A FAMILY OF LOGARITHMIC ESTIMATORS FOR POPULATION VARIANCE UNDER DOUBLE SAMPLING

Chandni Kumari, Ratan Kumar Thakur

Abstract

In this paper, an improved estimator for variance has been proposed to improvise the log-type estimators proposed by Kumari (2019). These classes of estimators provide a better alternative to the classes of estimators provided by Kumari (2019) as well as to some other commonly used estimators available in literature. A numerical study is included to support the use of the suggested classes of estimators.

Keywords
