摘要：The goal of this paper is to study the properties of a class of estimators of population variance based on multi-auxiliary variables proposed by Srivastava and Jhajj (1980), under the two different situations of random non-response advocated by Tracy and Osahan (1994). The results are obtained under the assumption that the number of sampling units on which information could not be obtained due to random non-response, follows some distribution; for instance, see Singh and Joarder (1998), Singh, Joarder and Tracy (2000), Singh (2003).
