Robust Estimation for Multivariate Wrapped Models
Giovanni Saraceno, Claudio Agostinelli, Luca Greco
A weighted likelihood technique for robust estimation of a multivariate Wrapped Normal distribution for data points scattered on a p-dimensional torus is proposed. The occurrence o…
Robust inference for nonlinear regression models from the Tsallis score: application to Covid-19 contagion in Italy
Paolo Girardi, Luca Greco, Valentina Mameli +4
We discuss an approach for fitting robust nonlinear regression models, which can be employed to model and predict the contagion dynamics of the Covid-19 in Italy. The focus is on t…
Weighted likelihood mixture modeling and model based clustering
Luca Greco, Claudio Agostinelli
A weighted likelihood approach for robust fitting of a mixture of multivariate Gaussian components is developed in this work. Two approaches have been proposed that are driven by a…
Weighted likelihood estimation of multivariate location and scatter
Claudio Agostinelli, Luca Greco
A novel approach to obtain weighted likelihood estimates of multivariate location and scatter is discussed. A weighting scheme is proposed that is based on the distribution of the…
