Independent random samples are taken from two normal populations with means μ1 and μ2 and a common unknown variance σ 2. It is known that μ1 ≤ μ2. In this paper, estimation of the common standard deviation σ is considered with respect to a scale invariant loss function. A general minimaxity result is proved and a class of minimax estimators is derived. An(More)
