This model can assume different shapes: unimodal or bimodal, symmetric or asymmetric. We discuss some properties of the model and perform a simulation study in order to assess the performance of the maximum likelihood estimators in finite samples. A real data application is also presented.Acceso Abiertoasymmetric distributionbimodal distributionmaximum likelihoodlocation-scale modelregression modelhttp://dx.doi.org/10.3390/sym13122279
