This measure is surprisingly associated with the sample variance in a way that leads to a new identity and interpretation of the notion of variance. | URI: | https://hdl.handle.net/20.500.14279/1168 | ISSN: | 10886826 | DOI: | 10.1090/S0002-9939-98-04524-9 | Rights: | © American Mathematical Society | Type: | Article | Affiliation : | Université de Montréal |
