Title: | A note on Tukey's polyefficiency | Authors: | Yatracos, Yannis G. | metadata.dc.contributor.other: | Γιατράκος, Γιάννης | Major Field of Science: | Engineering and Technology | Keywords: | Dimensional analysis;Efficiency;Robustness;Tukeys corners | Issue Date: | Sep-1991 | Source: | Biometrika, 1991, vol. 78, no. 3, pp. 702-703 | Volume: | 78 | Issue: | 3 | Start page: | 702 | End page: | 703 | Journal: | Biometrika | 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: | https://hdl.handle.net/20.500.14279/2141 | ISSN: | 14643510 | DOI: | 10.1093/biomet/78.3.702 | Rights: | © Oxford University Press | Type: | Article | Affiliation : | Université de Montréal |
