摘要
In this paper we investigate the robustness properties of the deepest regression, a method for linear regression introduced by Rousseeuw and Hubert [6]. We show that the deepest regression functional is Fisher-consistent fur the conditional median, and has a breakdown value of 1/3 in all dimensions. We also derive its influence function, and compare it with sensitivity functions. (C) 2000 Academic Press.
