Let U/sub 1/,U/sub 2/,...,U/sub N/ be the N units of a finite population and let (y/sub i/,x/sub i/) be a vector of nonnegative components associated with the i/sup th/ unit, where the x's are known and the y's are unknown. A sample of fixed size n( 2. When a suitable variable x, which is directly proportional to the variable of interest y, is not available, one may know how to rank units reasonably well relative to the unknown y values before sample selection. When such ranking is possible, we introduce a simple and efficient ..pi..pswor sampling plan for general n using the ranks as the known x measures of size.
