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.

A guide to survival of momentum in UK style portfolios [PDF]

open access: yes, 2018
In this study we estimate the survival time of momentum in six UK style portfolio returns from October 1980 to June 2014. We utilise the Kaplan-Meier estimator, a non-parametric method that measures the probability that momentum will persist beyond the ...

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

On consistency of kernel density estimators for randomly censored data : rates holding uniformly over adaptive intervals [PDF]

open access: yes, 2001
. – In the usual right-censored data situation, let fn, n ∈ N, denote the convolution of the Kaplan–Meier product limit estimator with the kernels a−1n K(·/an), where K is a smooth probability density with bounded support and an → 0.

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.

Outcomes and Surgical Management of Malignant Rhabdoid Tumor of the Kidney: A Report From the Pediatric Surgical Oncology Research Collaborative

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Malignant rhabdoid tumor of the kidney (MRTK) is a rare, aggressive tumor seen in young children. The optimal timing of resection for locally advanced tumors is not well‐defined. The purpose of this study is to evaluate modern oncologic outcomes and the impact of surgical timing. Methods A multicenter retrospective review was performed

Asymptotically local minimax estimation of infinitely smooth density with censored data [PDF]

open access: yes, 1996
The problem of the nonparametric minimax estimation of an innitely smooth density at a given point, under random censorship, is considered. We establish the exact limiting behavior of the local minimax risk and propose the ecient kernel -type estimator ...

ESTIMACIÓN DE KAPLAN MEIER BOOTSTRAP DE LA CURVA DE SUPERVIVENCIA

open access: yesPesquimat, 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.

A nonparametric model-based estimator for the cumulative distribution function of a right censored variable in a finite population [PDF]

open access: yes, 2014
In survey analysis, the estimation of the cumulative distribution function (cdf) is of great interest: it allows for instance to derive quantiles estimators or other non linear parameters derived from the cdf.
