SpletEl nombre de Gauss se ha asociado a esta distribución porque la usó con profusión cuando analizaba datos astronómicos 6 y algunos autores le atribuyen un descubrimiento independiente del de De Moivre. 7 Esta atribución del nombre de la distribución a una persona distinta de su primer descubridor es un claro ejemplo de la ley de Stigler . SpletThe Formula That Killed Wall Street: that was how Wired’s editors introduced the Gaussian copula to the readers of a February 2009 article by journalist Felix Salmon.
