Robust Estimations of Survival Function for Weibull Distribution

Statistica, 2021
The aim of this study is to estimate the robust survival function for the Weibull distribution. Since the survival function of Weibull distribution is based on the parameters, we consider two robust and explicit Weibull parameter estimators proposed by ...

The time to degree or dropout amongst full-time master’s students at University of KwaZulu-Natal

South African Journal of Science, 2015
Universities around the world are grappling with strategies to increase throughput and minimise dropout rates of postgraduate students. This study focuses on students at the University of KwaZulu-Natal and we attempt to estimate the time that it takes ...

Nonparametric Estimation of a Recurrent Survival Function [PDF]

Journal of the American Statistical Association, 1999
Recurrent event data are frequently encountered in studies with longitudinal designs. Let the recurrence time be the time between two successive recurrent events. Recurrence times can be treated as a type of correlated survival data in statistical analysis.

Latent diffusion models for survival analysis [PDF]

, 2010
We consider Bayesian hierarchical models for survival analysis, where the survival times are modeled through an underlying diffusion process which determines the hazard rate.

Quantile Regression with a New Exponentiated Odd Log-Logistic Weibull Distribution

Mathematics, 2023
We define a new quantile regression model based on a reparameterized exponentiated odd log-logistic Weibull distribution, and obtain some of its structural properties.

The utility of liver function tests for mortality prediction within one year in primary care using the algorithm for liver function investigations (ALFI) [PDF]

, 2012
BACKGROUND: Although liver function tests (LFTs) are routinely measured in primary care, raised levels in patients with no obvious liver disease may trigger a range of subsequent expensive and unnecessary management plans.

Estimation of Survival Function [PDF]

Acta Oeconomica Pragensia, 2007
Aplikace analýzy dat o "přežiti" (survival data) zaznamenala velký rozvoj a metody analýzy přežiti se rozsiřily z oblasti biomediciny a techniky do řady dalsich oborů. Problemu odhadu pravděpodobnostniho rozděleni doby do výskytu urciteho jevu v připadě, kdy jsou k dispozici cenzorovana data, je věnovana znacna pozornost.
