Checking unimodality using isotonic regression: an application to breast cancer mortality rates
Rueda, C.; Ugarte Martínez, María Dolores ; Militino, Ana F. (Springer, 2016)
Artículo / Artikulua
In some diseases it is well-known that a unimodal mortality pattern exists. A clear example in developed countries is breast cancer, where mortality increased sharply until the nineties and then decreased. This clear ... -
