An alternative estimator for multi-character surveys

Abstract.

In this paper, an alternative estimator for estimating population totals in multi-character survey sampling has been suggested when certain variables have poor positive correlation and others have poor negative correlation with selection probabilities. The estimators proposed by Hansen and Hurwitz (1943), Rao (1966) and Sahoo et al. (1994) are shown as special cases of the proposed estimator. The relative efficiency of the proposed estimator with respect to these estimators has been studied through empirical study.
