A Product-Limit Estimator of the Conditional Survival Function When Cure Status Is Partially Known
Safari, Wende Clarence; López-de-Ullibarri, Ignacio; Jácome, M. A. (Wiley, 2021-03-01)[Abstract] We introduce a nonparametric estimator of the conditional survival function in the mixture cure model for right-censored data when cure status is partially known. The estimator is developed for the setting of a ... -
Feasibility, efficacy and safety of early lens extraction in patients with pseudoexfoliation glaucoma: a feasibility and pilot study
Pose-Bazarra, Sara; López-Valladares, María Jesús; López-de-Ullibarri, Ignacio; Azuara-Blanco, Augusto Augusto (Springer Nature, 2023-09)[Abstract]:PURPOSE: To evaluate the feasibility of a trial to compare the efficacy and safety of initial lens extraction surgery versus medical treatment for people with pseudoexfoliation glaucoma (PXFG) or ocular ... -
Nonparametric Kernel Estimation of the Probability of Cure in a Mixture Cure Model when the Cure Status is Partially Observed
Safari, Wende Clarence; López-de-Ullibarri, Ignacio; Jácome, M. A. (Sage, 2022-08-01)[Abstract] Cure models are a class of time-to-event models where a proportion of individuals will never experience the event of interest. The lifetimes of these so-called cured individuals are always censored. It is usually ... -
npcure: An R Package for Nonparametric Inference in Mixture Cure Models
López-Cheda, Ana; Jácome, M. A.; López-de-Ullibarri, Ignacio (Technische Universitaet Wien, 2021)[Abstract] 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 (cured subjects). So, the goal ... -
survPresmooth: An R Package for Presmoothed Estimation in Survival Analysis
López-de-Ullibarri, Ignacio; Jácome, M. A. (American Statistical Association, 2013-08)[Abstract] The survPresmooth package for R implements nonparametric presmoothed estimators of the main functions studied in survival analysis (survival, density, hazard and cumulative hazard functions). Presmoothed versions ... -
Wastewater early warning system for SARS-CoV-2 outbreaks and variants in a Coruña, Spain
Trigo-Tasende, Noelia; Vallejo, Juan Andrés; Rumbo-Feal, Soraya; Conde-Pérez, Kelly; Vaamonde, Manuel; López-Oriona, Ángel; Barbeito, Inés; Nasser-Ali, Mohammed; Reif López, Rubén; Rodiño-Janeiro, Bruno Kotska; Fernández-Álvarez, Elisa; Iglesias Corrás, Iago; Tarrío-Saavedra, Javier; Tomás, Laura; Gallego-García, Pilar; Posada, David; Bou, Germán; López-de-Ullibarri, Ignacio; Cao, Ricardo; Susana, Ladra; Poza, Margarita (Springer, 2023-07)[Abstract]: Wastewater-based epidemiology has been widely used as a cost-effective method for tracking the COVID-19 pandemic at the community level. Here we describe COVIDBENS, a wastewater surveillance program running ...
