On the Construction of Non­Invariant Balanced Sampling Designs

Abstract

The problem of constructing non­invariant balanced sampling designs of fixed effective size has been considered and solutions have been suggested to cover all possible combinations of values of the population and the sample sizes, The methods also illustrate that fixed effective size designs can easily be constructed with constant inclusion probabilities of first two orders and with the number of possible samples much smaller than that for the usual SRSWOR procedure.
