Abstract
Given a collection of nested closed, convex symmetric sets and a linea r functional, we find estimates which are within a logarithm term of b eing simultaneously asymptotically minimax. Moreover, these estimates can be constructed so that the loss of this logarithm term only occurs on a small subset of functions. These estimates are quasi-optimal sin ce there do not exist estimators which do not lose a logarithm term on some part of the parameter spaces.
