Abstract

We consider a wide class of estimates which present some formal analogy with

The well-known L-estimates. We obtain the following results:

The qualitative robustness is proved and the influence function is computed under mild conditions.

A Theorem on asymptotic normality and asymptotic validity of FRECHET-CRAMER-RAO-bound is shown.

A particular subclass of estimates is considered: the corresponding breakdown point is ootameci arm. some simulation results are given
Keywords: Influence curve; breakdown point; asymptotic normality; location estimates; statistical functionals; FRECHET differential
