Partially Linear Additive Hazards Regression for Bivariate Interval-Censored Data

open access: yesAxioms, 2023
In this paper, we discuss regression analysis of bivariate interval-censored failure time data that often occur in biomedical and epidemiological studies. To solve this problem, we propose a kind of general and flexible copula-based semiparametric partly

Confidence intervals for ratio of means of delta-lognormal distributions based on left-censored data with application to rainfall data in Thailand [PDF]

open access: yesPeerJ, 2023
Thailand is a country that is prone to both floods and droughts, and these natural disasters have significant impacts on the country’s people, economy, and environment. Estimating rainfall is an important part of flood and drought prevention.

Bayesian Analysis of Clustered Interval-censored Data [PDF]

open access: yesJournal of Dental Research, 2005
The recording of multiple interval-censored failure times is common in dental research. Modeling multilevel data has been a difficult task. This paper aims to use the Bayesian approach to analyze a set of multilevel clustered interval-censored data from a clinical study to investigate the effectiveness of silver diamine fluoride and sodium fluoride ...

CTIVA: Censored time interval variable analysis.

open access: yesPLoS ONE, 2023
Traditionally, datasets with multiple censored time-to-events have not been utilized in multivariate analysis because of their high level of complexity.

Bayesian Estimations of Exponential Distribution Based on Interval-Censored Data with a Cure Fraction

open access: yesJournal of Mathematics, 2021
Censored data are considered to be of the interval type where the upper and lower bounds of an event’s failure time cannot be directly observed but only determined between interval inspection times.

Variable Selection for Length-Biased and Interval-Censored Failure Time Data

open access: yesMathematics, 2023
Length-biased failure time data occur often in various biomedical fields, including clinical trials, epidemiological cohort studies and genome-wide association studies, and their analyses have been attracting a surge of interest.

A semiparametric cure model for interval‐censored data [PDF]

open access: yesBiometrical Journal, 2013
There is a growing interest in the analysis of survival data with a cured proportion particularly in tumor recurrences studies. Biologically, it is reasonable to assume that the recurrence time is mainly affected by the overall health condition of the patient that depends on some covariates such as age, sex, or treatment type received.

Empirical Density Estimation for Interval Censored Data

open access: yesAustrian Journal of Statistics, 2016
This paper is concerned with the nonparametric estimation of a density function when the data are incomplete due to interval censoring. The Nadaraya-Watson kernel density estimator is modified to allow description of such interval data.

Stochastic EM algorithm for doubly interval-censored data [PDF]

open access: yesBiostatistics, 2013
In clinical trials, it is frequently of interest to estimate the time between the onset of two events (e.g. duration of response in oncology). Here, we consider the case where subjects are assessed at fixed visits but the initial event and the terminating event occur in between visits.
