coucou @niiinou! j'ai noté que  "L’estimateur T d’un paramètre θ est dit convergent si la variance de T diminue quand la taille de l’échantillon augmente" alors que "L’estimateur T d’un paramètre θ est dit sans biais si l’espérance de T est égale à la valeur θ

 

du coup je pense ça ne se signifie pas que l'estimateur est convergent ni qu'il est sans biais!
