Comparison of nonparametric estimators versus parametric for reliability function

open access: yesIngeniería 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.

Identification of a Novel Prognostic Gene Signature From the Immune Cell Infiltration Landscape of Osteosarcoma

open access: yesFrontiers in Cell and Developmental Biology, 2021
Background: The tumor microenvironment (TME) mainly comprises tumor cells and tumor-infiltrating immune cells mixed with stromal components. Latestresearch hasdisplayed that tumor immune cell infiltration (ICI) is associated with the clinical outcome of ...

Bootstrapping the Kaplan–Meier estimator on the whole line [PDF]

open access: yesAnnals of the Institute of Statistical Mathematics, 2018
This article is concerned with proving the consistency of Efron's (1981) bootstrap for the Kaplan-Meier estimator on the whole support of a survival function. While other works address the asymptotic Gaussianity of the estimator itself without restricting time (e.g.

Sensitivity of Survival Analysis Metrics

open access: yesMathematics, 2023
Survival analysis models allow for predicting the probability of an event over time. The specificity of the survival analysis data includes the distribution of events over time and the proportion of classes.

Meteorological and Agricultural Drought Risk Assessment via Kaplan–Meier Survivability Estimator

open access: yesAgriculture
Dry periods and drought are inherent natural occurrences. However, due to the increasing pressures of global warming and climate change, these events have become more frequent and severe on a global scale.

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

open access: yesStatistical 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.

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

open access: yesStats, 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

Subtype‐specific enhancer RNAs define transcriptional regulators and prognosis in breast cancers

open access: yesMolecular Oncology, EarlyView.
This study employed machine learning methodologies to perform the subtype‐specific classification of RNA‐seq data sets, which are mapped on enhancers from TCGA‐derived breast cancer patients. Their integration with gene expression (referred to as ProxCReAM eRNAs) and chromatin accessibility profiles has the potential to identify lineage‐specific and ...
