Codice 06/2017 Titolo On the Use of the Concentration Function in Medical Fraud Assessment Data 2017-01-27 Autore/i Ekin, T.; Ieva, F.; Ruggeri, F.; Soyer, R. Link Download full text Pubblicato The American Statistician Abstract We propose a simple, but effective, tool to detect possible anomalies in the services prescribed by a health care provider (HP) compared to his/her colleagues in the same field and environment. Our method is based on the concentration function which is an extension of the Lorenz curve widely used in describing uneven distribution of wealth in a population. The proposed tool provides a graphical illustration of a possible anomalous behavior of the HPs and it can be used as a pre-screening device for further investigations of potential medical fraud.
