[1706.10062] Barankin Vector Locally Best Unbiased Estimates

WebThe Barankin bound was derived from the Schwarz inequality, in a manner much like (6), by Kiefer [7]. One of the reviewers pointed out that the Barankin formulation can be specialized to include all the bounds for unbiased estimation, e.g., the Bhatta- charyya bounds. The formulation in this correspondence is WebWe show that, under mild conditions, the Barankin bound (the tightest possible lower bound on the estimator variance) is a lower semi-continuous function ofthe parameter vector. We also show that the RKHS associated with an MVE problem remains unchanged if the observation is replaced by a sufﬁcient statistic.
