Dans cet article, nous considérons le problème de l'estimation robuste de certains paramètres relatifs à une distribution multivariée lognormale. Dans ce but, nous construisons une classe d'estimateurs et donnons certaines de leurs propriétés telles que la consistence au sens de Fisher, la robustesse et la normalité asymptotique.

In this paper we consider the problem of robust estimation of some parameters related to a multivariate lognormal distribution. In this sense, we construct a class of estimators and discuss some of its properties, such as Fisher consistency, robustness and asymptotic normality.
