Evaluation of the Duration of Unemployment Spells Using Kaplan-Meier Estimator. A study on Botoşani County’s Labor Market [PDF]

Ovidius University Annals: Economic Sciences Series, 2018
The aim of this paper is analysing unemployment spells for Botoşani County’s labour market. The database includes individual information on a sample of 200 unemployment spells registeredat the Employment Agency of Botoşani County during January 2012 ...

Modified Weighted Kaplan-Meier Estimator

Pakistan Journal of Statistics and Operation Research, 2007
En muchos estudios médicos, la mayoría de los sujetos del estudio no llegan al evento de interés durante el período de estudio. En tales situaciones, el estimador de Kaplan Meier puede estimar las probabilidades de supervivencia para la observación censurada.

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

Agriculture
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.

Delta method in large deviations and moderate deviations for estimators [PDF]

, 2011
The delta method is a popular and elementary tool for deriving limiting distributions of transformed statistics, while applications of asymptotic distributions do not allow one to obtain desirable accuracy of approximation for tail probabilities.

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

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.

Adherence to Protocol Recommendations for Children With Wilms Tumour in Two Consecutive Studies in the United Kingdom and Ireland—Does Variation Matter?

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background and Aims Wilms tumour (WT) has excellent event‐free and overall survival (OS). However, small differences exist between countries participating in the same international study. This led us to examine variation in adherence to protocol recommendations as a potential contributing factor.

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.

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

, 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.

Semiparametric inference for the recurrent event process by means of a single-index model [PDF]

, 2014
In this paper, we introduce new parametric and semiparametric regression techniques for a recurrent event process subject to random right censoring. We develop models for the cumula- tive mean function and provide asymptotically normal estimators.
