Resumen
Ce travail présente une image générale sur l’estimation de l’ecart-type pour une population normale.
Des commentaires spéciales sont dediés aux estimaterus linéaires qui sont construits à l’aide de ce qu’on appele “quasi-ranges”.
Dans le dernier part de cet article, un estimateur de ce type est construit avec les propriétés: 1) asymptotique sans bias; 2) asymptotique conformable.
On determine un coefficient avec la propriété que l’estimateur devienne un estimateur avec erreur moyenne carrée minimume.
Quelques exemples et tables sont données.
