Abstract

The sampling scheme proposed by Srivastava and Singh depends upon a specific split of the sizes and most of the Πij's do not satisfy the condition of non-negativity of variance estimates as suggested by Hanurav. Using the information about the nature of non-negativity condition (Øij>0) approach, Dwivedi provided split of sizes with less number of trials which gives a set of Πij's satisfying the condition of non-negativity of variance estimates. This paper provides an algorithm for a proper split of sizes which gives a set of Πij's such that the condition of non-negativity of variance estimates is nearly satisfied. It is also shown that on an average the relative efficiency of proposed algorithm shows the superiority over PPSWR.
