Abstract: | It Is illustrated that the adaptation of robust estimators, Tiku's (1967, 1978, 1980) modified maximum likelihood estimators for example, in sample survey can lead to considerable improvements In efficiencies in estimating the mean of a finite population (a random sample of Independent observations from a super-popularlon). In this paper, however, we confine our attention to symmetric super-populations |
