Simultaneous confidence sets for ranks using the partitioning principle - Technical report
Diaa Al Mohamad, Erik W. van Zwet, Jelle J. Goeman +1
Ranking institutions such as medical centers or universities is based on an indicator accompanied with an uncertainty measure such as a standard deviation, and confidence intervals…
Estimation of parametric and semiparametric mixture models using phi-divergences
Diaa Al Mohamad
The study of mixture models constitutes a large domain of research in statistics. In the first part of this work, we present phi-divergences and the existing methods which produce…
Two Iterative Proximal-Point Algorithms for the Calculus of Divergence-based Estimators with Application to Mixture Models
Diaa Al Mohamad, Michel Broniatowski
Estimators derived from an EM algorithm are not robust since they are based on the maximization of the likelihood function. We propose a proximal-point algorithm based on the EM al…
A Proximal Point Algorithm for Minimum Divergence Estimators with Application to Mixture Models
Diaa Al Mohamad, Michel Broniatowski
Estimators derived from a divergence criterion such as divergences are generally more robust than the maximum likelihood ones. We are interested in particular in the so-called…
