Abstract
The problem of robust estimation of the common scale parameter of several Pareto distributions with unknown and possibly unequal shape parameters is considered. In this paper, a wide class of estimators dominating the maximum likelihood estimator (MLE) is derived under a class of convex loss functions. The problem discussed in this paper arises quite frequently in socio-economics, reliability, life testing, and survival analysis.Pareto distribution Common scale parameter Convex loss function
