Abstract

Abstract: Sequential sampling plans for unbiased estimation of the Bernoulli parameter ' p ' and its functions have been studied almost 70 years back. An extension of the idea to parametric function estimation in a tetranomial distribution has been considered in this paper. The cell probabilities are taken to be p 2, q 2, r 2 and 2( pq + pr + qr ), satisfying p, q, r > 0, p + q + r = 1. Some illustrative examples have been studied to demonstrate the underlying concepts and the computational procedure. The emphasis is on unbiased estimation in the exact sense which makes it difficult and challenging.
