On the Least-Informative Distribution in a Contamination Neighborhood.
Abstract
For a board class of model distributions G, this document determines the distribution minimizing Fisher information for location in the epsilon-contamination neighborhood of G. The class consists of distributions G with a density g such that psi sub g = -g'/g is continuously differentiable and psi ' sub g has finitely many intervals of increase. The result is extended to the scale problem. Keywords: Robust estimation. (Author)
