| Abstract: | In this paper, we first propose a new estimator--generalized ratio estimator (GRE) and make a comparison between GRE and generalized difference estimator (GDE) proposed by Cassel, Sarndal and Wretman (1976, 1977). Then we discuss the optimality of GRE and GDE. Finally, a meaningful application is given. |
