In this paper we consider three well-known procedures of unequal probability sampling without replacement. Using an asymptotic approach, Hartley and Rao [3] have obtained compact expressions for ...

It is shown that sampling without replacement with probability proportional to size can be achieved if the units are grouped with reference to size. When the same unit is chosen a second time, it is ...
