Abstract
A gradient-like statistic recently introduced as an influence measure has been showed to work well in large sample, thanks to its asymptotic properties. In this work, through small-scale simulation schemes, the performnance of such a diagnostic measure is further investigated in terms of concordance with the main influence measures in outlier identification. The simulation studies are performed by using Generalized Linear Mixed Models.
