Survival Methods for Correlated Time-to-Event Data
The use of product-limit (Kaplan-Meier) estimation and Cox proportional hazards modeling is common when analyzing timeto-event data, especially in the presence of censoring. Presenting results from both methods provides the magnitude of loss within the levels of a given variable, and a relative measure of failure risk between the levels. However, since both above methods assume independence of ...
متن کاملComparison of time to the event and nonlinear regression models in the analysis of germination data
Extended abstract Introduction: Numerous studies are being carried out to reveal the effects of different treatments on the germination of seeds from various plants. The most commonly used method of analysis is the nonlinear regression which estimates germination parameters. Although the nonlinear regression has been performed based on different models, some serious problems in its structure...
متن کاملSurvival curve estimation for informatively coarsened discrete event-time data.
Interval-censored, or more generally, coarsened event-time data arise when study participants are observed at irregular time periods and experience the event of interest in between study observations. Such data are often analysed assuming non-informative censoring, which can produce biased results if the assumption is wrong. This paper extends the standard approach for estimating survivor funct...
متن کاملP 8: Affective Factors in the Event Time of Neuropathy in Diabetic Patients (Type II)
Introduction: Neuropathy is a common complication of diabetes that can cause disability in diabetic patients. The aim of this study was to determine of affective factors in the Event Time of Neuropathy in type 2 diabetes using Cox proportional hazards model. Materials and Methods: This study included 371 patients with type II diabetes without neuropathy who were registered at Fereydunshahr diab...
متن کاملEvent history graphs for censored survival data.
A compact graphical device for combining survival and time-varying covariate information is proposed. The proposed graph contains the Kaplan-Meier estimator for right-censored data and a simultaneous display of the behaviour of time-dependent covariate(s) and the lifetime for each subject in the sample. The observed levels of time-dependent covariates are possibly subjected to an initial dimens...
