Responder Identification in Clinical Trials with Censored Data [PDF]
, 2003 We present a newly developed technique for identification of positive and negative responders to a new treatment which was compared to a classical treatment (or placebo) in a randomized clinical trial.

Assessment of left-censored data treatment methods using stochastic simulation
RBRH, 2023 The paper evaluates the influence of size series, percentage of censored data, and coefficients of variation used to generate synthetic series on the estimation of means, standard deviations, coefficients of variation, and medians in series with censored

TL-Moments for Type-I Censored Data with an Application to the Weibull Distribution
Mathematical and Computational Applications, 2018 This paper aims to provide an adaptation of the trimmed L (TL)-moments method to censored data. The present study concentrates on Type-I censored data. The idea of using TL-moments with censored data may seem conflicting. However, our perspective is that

Gross alpha and beta activities in drinking water from Goiás state, Brazil
Brazilian Journal of Radiation Sciences, 2019 Detection of gross alpha and beta radioactivity is important for a quick surveying of both natural and anthropogenic radioactivity in water. Furthermore, gross alpha and gross beta parameters are included in Brazilian legislation on quality of drinking ...

Maximum-Likelihood Estimation of a Log-Concave Density based on Censored Data [PDF]
, 2014 We consider nonparametric maximum-likelihood estimation of a log-concave density in case of interval-censored, right-censored and binned data. We allow for the possibility of a subprobability density with an additional mass at $+\infty$, which is ...

Weighted Empirical Likelihood for Accelerated Life Model with Various Types of Censored Data
StatsIn analysis of survival data, the Accelerated Life Model (ALM) is one of the widely used semiparametric models, and we often encounter various types of censored survival data, such as right censored data, doubly censored data, interval censored data ...

Testing for mechanistic interactions in long-term follow-up studies. [PDF]
PLoS ONE, 2015 In follow-up studies, interactions are often assessed by including a cross-product term in a (multiplicative) Cox model. However, epidemiologists/clinicians often misinterpret a significant multiplicative interaction as a genuine mechanistic interaction.

Reliability Analysis of Military Vehicles Based on Censored Failures Data
Applied Sciences, 2022 The paper proposes a methodology of reliability testing as applied to vehicles used in military transport systems. After estimating the value of the reliability function using the Kaplan–Meier estimator, reliability models were developed and analysed ...

Tratamento de dados censurados em estudos ambientais
Química Nova, 2014 Due to the inherent limitations of the analytical methods of measurement, environmental exposure data often present observations described as below a certain detection limit, also called left-censored data. Censored data directly interferes in almost all
