npcure: An R Package for Nonparametric Inference in Mixture Cure Models

Ana López-Cheda, M. Amalia Jácome, Ignacio López-de-Ullibarri

Mixture cure models have been widely used to analyze survival data with a cure fraction. They assume that a subgroup of the individuals under study will never experience the event…

Nonparametric covariate hypothesis tests for the cure rate in mixture cure models

Ana López-Cheda, M. Amalia Jácome, Ingrid Van Keilegom +1

In lifetime data, like cancer studies, theremay be long term survivors, which lead to heavy censoring at the end of the follow-up period. Since a standard survival model is not app…

Nonparametric latency estimation for mixture cure models

Ana López-Cheda, M. Amalia Jácome, Ricardo Cao

A nonparametric latency estimator for mixture cure models is studied in this paper. An i.i.d. representation is obtained, the asymptotic mean squared error of the latency estimator…

Estimating lengths-of-stay of hospitalised COVID-19 patients using a non-parametric model: a case study in Galicia (Spain)

Ana López-Cheda, M. Amalia Jácome, Ricardo Cao +1

Estimating the lengths-of-stay (LoS) of hospitalised COVID-19 patients is key for predicting the hospital beds' demand and planning mitigation strategies, as overwhelming the healt…
