biological, agricultural, economic, and reliability experiments. Consider a bivariate normal
population with unknown mean (θ1, θ2), known variances, and known correlation coefficient
ρ, where θ1⩽ θ2. The problem of estimation of (θ1, θ2) is studied when the loss function
used is sum of squared errors. We have considered two cases: equal variances and
unequal variances. In both cases, a class of minimax estimators is proposed. These …
