This paper proposes a class of estimators for estimating the finite population mean " Y of a study variate y using information on two auxiliary variates, one of which is positively and the other negatively correlated with the study variate y. An Βͺasymptotically optimum estimatorΒΊ (AOE) in the class
We consider the problem of estimating a \(p\)-dimensional vector \(\mu_{1}\) based on independent variables \(X_{1}, X_{2}\), and \(U\), where \(X_{1}\) is \(N_{p}\left(\mu_{1}, \sigma^{2} \Sigma_{1}\right), X_{2}\) is \(N_{p}\left(\mu_{2}, \sigma^{2} \Sigma_{2}\right)\), and \(U\) is \(\sigma^{2} \
Two eetimators, one additive the other multiplicative. are conaidered for mean frequenoiee in a complete three-way table. Ueing the mean equare error criterion it is ehown that preference for the additive eatimator can be as high 7/8 in tablee with row-column independence and in homogeneour tables.
