Comparison of nonparametric estimators versus parametric for reliability function

Ingeniería Investigación y Desarrollo, 2015
One of the main objectives of the area of realiability is to estimate the function of reliability, where traditionally are used non parametric estimators, being more efficient in sample of big sizes.

A Brief Overview of Restricted Mean Survival Time Estimators and Associated Variances

Stats, 2020
Restricted Mean Survival Time ( R M S T ) experiences a renaissance and is advocated as a model-free, easy to interpret alternative to proportional hazards regression and hazard rates with implication in causal inference. Estimation of R M S T

The Kaplan–Meier estimator as a sum over units

Discover Data
A sum-wise formulation is proposed for the Kaplan–Meier product limit estimator of partially right-censored survival data. The population estimator is expressed as a sum over the individual units’ empirical and semi-empirical contributions, for observed ...

Asymptotic properties of Kaplan–Meier estimator and hazard estimator for censored survival time with LENQD data

Statistical Theory and Related Fields
In this paper, we consider the estimators of distribution function and hazard rate for censored survival time. First, some properties and inequalities are established for linearly extended negative quadrant-dependent sequence as auxiliary results.

Pediatric Idiopathic Multicentric Castleman Disease Is Often Severe But Responsive to Siltuximab

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Idiopathic multicentric Castleman disease (iMCD) is a potentially fatal immunologic disorder marked by widespread lymphadenopathy and inflammation. Siltuximab, an interleukin‐6 (IL‐6) inhibitor, is the only FDA‐approved treatment for adult patients with iMCD.

The Impact of the COVID‐19 Pandemic on Childhood Cancer Survival: A Population‐Based Assessment of Survival Patterns Between 2015 and 2023 in Germany

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Numerous international studies have reported declines in new cancer diagnoses, delayed diagnoses and disruptions in cancer treatment following the implementation of COVID‐19 pandemic public health measures, raising concerns that these effects may ultimately contribute to increased cancer mortality.

A berry-essen inequality for the kaplan-meier L-estimator

, 2001
Let ({hat F}_n) be the Kaplan-Meier estimator of distribution function F. Let J(·) be a measurable real-valued function. In this paper, a U-statistic representation for the Kaplan-Meier L-estimator, (T({hat F}_n) = int xJ({hat F}_n(x)) d{hat F}_n(x)), is

Venetoclax‐Based Therapy as a Bridge to Hematopoietic Stem Cell Transplantation in Relapsed or Refractory Pediatric Acute Leukemia

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Relapsed and/or refractory (R/R) pediatric acute leukemia carries a dismal prognosis, largely driven by chemoresistance to conventional salvage therapy. The BH3‐mimetic venetoclax, combined with chemotherapy or hypomethylating agents, has demonstrated efficacy in small clinical trials.

ESTIMACIÓN DE KAPLAN MEIER BOOTSTRAP DE LA CURVA DE SUPERVIVENCIA

Pesquimat, 2014
In this work the function of survival is estimated by means of the non-parametric method known like the Kaplan Meier Bootstrap estimator, under the assumption of asymptotical normality.
