|Title:||A note on Tukey's polyefficiency||Authors:||Yatracos, Yannis G.||Keywords:||Dimensional analysis||Issue Date:||1991||Publisher:||Oxford University Press||Source:||Biometrika, 1991, Volume 78, Issue 3, Pages 702-703||Abstract:||The efficiency of an estimate Sn is usually computed at some underlying distribution. Because it is rare that a real situation can be represented by a single assumed model, Tukey proposed to compute instead the polyefficiency of Sn, that is the infimum of the efficiencies of Sn at a reasonable collection of distributions called corners. It is shown that high polyefficiency over a finite number of corners, seen as possible distributions of the n dimensional sample, implies at least as high an efficiency at any convex combination of these corners.||URI:||http://ktisis.cut.ac.cy/handle/10488/6701||ISSN:||0006-3444 (print)
