A Bayesian Semiparametric Temporally-Stratified Proportional Hazards Model with Spatial Frailties
(INT SOC BAYESIAN ANALYSIS, 2012)
Likelihood approximations and discrete models for tied survival data
(Marcel Dekker Inc, 2014)
Characterization of the variable cow's age at last calving as a measurement of longevity by using the Kaplan-Meier estimator and the Cox model
In most studies on beef cattle longevity, only the cows reaching a given number of calvings by a specific age are considered in the analyses. With the aim of evaluating all cows with productive life in herds, taking into ...
Choosing between Cox proportional hazards and logistic models for interval-censored data via bootstrap
(Carfax Publishing, 2003-01-01)
This work develops a new methodology in order to discriminate models for interval-censored data based on bootstrap residual simulation by observing the deviance difference from one model in relation to another, according ...
Tests of proportional hazards and proportional odds models for grouped survival data
(International Biometric Soc, 2014)
A semi-Markov multistate model for estimation of the mean quality-adjusted survival for non-progressive processes
We discuss the estimation of the expected value of the quality-adjusted survival, based on multistate models. We generalize an earlier work, considering the sojourn times in health states are not identically distributed, ...
Estimation of the mean quality-adjusted survival using a multistate model for the sojourn times
(ELSEVIER SCIENCE BV, 2008)
In clinical trials, it may be of interest taking into account physical and emotional well-being in addition to survival when comparing treatments. Quality-adjusted survival time has the advantage of incorporating information ...
