Efficiency of a new estimator in PPS sampling for multiple characteristics. (English) Zbl 0675.62007
Summary: M. L. Bansal and R. Singh [ibid. 11, 313-320 (1985; Zbl 0563.62007)] have developed an alternative estimator for the probability proportional to size with replacement sampling scheme when certain characteristics under study are poorly correlated with the selection probabilities. We suggest, in this paper, a more intuitive and meaningful estimator and study its efficiency compared with other related estimators.
