      [Abstract]: In lifetime data, like cancer studies, there may be long term survivors, which lead to heavy censoring at the end of the follow-up period. Since a standard survival model is not appropriate to handle these data, ...
    • Nonparametric Estimation in Mixture Cure Models with Covariates 

      López-Cheda, Ana; Peng, Yingwei; Jácome, M. A. (Springer Nature, 2023-05-17)
