A dynamic model for the risk of bladder cancer progression
(2012)We propose a multistate modeling approach to describe the observed evolution of patients diagnosed with nonmuscle- invasive bladder cancer. On the basis of data from the Spanish Bladder Cancer/EPICURO ... -
A generalized Fleming and Harrington’s class of tests for interval-censored data
(2012)The class Gρ,λ of weighted log-rank tests proposed by Fleming & Harrington [Fleming & Harrington (1991) Counting Processes and Survival Analysis, Wiley, New York] has been widely used in survival ... -
The Analysis of interval censoring and double censoring via Markov chain Monte Carlo methods
(2002-05-31)L'Anàlisi de la supervivència s'utilitza en diferents camps per analitzar el temps transcorregut entre dos esdeveniments. El que distingeix l'anàlisi de la supervivència d'altres àrees de l'estadística ... -
Incertesa i coneixement
(2005)Incertesa i coneixement són dos conceptes oposats, antagònics, però que molt sovint es veuen obligats a conviure. La seva gran rivalitat serà una constant que els acompanyarà en tot moment,cadascun ... -
Interval censoring: identifiability and the constant-sum property
(2007)The constant-sum property given in Oller et al. (2004) for censoring models justifies the use of a simplified likelihood to obtain the nonparametric maximum likelihood estimator of the lifetime ... -
Interval censoring: model characterizations for the validity of the simplified likelihood
(2004)En analyse de durées de vie, le problème de la censure par intervalle a généralement été traité par des méthodes vraisemblantistes. Comme la vraisemblance est complexe, on suppose souvent que les ... -
Likelihood inferences with interval-censored data
(2003-04-28)En l’anàlisi de la supervivència el problema de les dades censurades en un interval es tracta, usualment,via l’estimació per màxima versemblança. Amb l’objectiu d’utilitzar una expressió simplificada ... -
A Multi-state model for the analysis of functional decline and mortality of frail elderly patients
(2004-10-29)L’objectiu d’aquest estudi, que correspon a un projecte de recerca sobre la pèrdua funcional i la mortalitat de persones grans fràgils, és construir un procés de supervivència predictiu que tingui en ... -
Nonparametric Bayesian estimation from interval-censored data using Monte Carlo methods
(2001)We study the estimation of the survival function based on interval-censored data from a nonparametric Bayesian point of view. Interval censoring arises when the time variable of interest cannot be ... -
Number of consumers necessary for shelf life estimations based on survival analysis statistics
(2007)Survival analysis statistics have been used to estimate shelf life of foods based on consumers’ acceptance or rejection of samples with different storage times. The interval censored nature of the data ... -
Tutorial on methods for interval-censored data and their implementation in R
(2009)Interval censoring is encountered in many practical situations when the event of interest cannot be observed and it is only known to have occurred within a time window. The theory for the analysis of ...
