A new approach to modeling the cure rate in the presence of interval censored data

We consider interval censored data with a cured subgroup that arises from longitudinal followup studies with a heterogeneous population where a certain proportion of subjects is not susceptible to the event of...

Improving marginal hazard ratio estimation using quadratic inference functions

Clustered and multivariate failure time data are commonly encountered in biomedical studies and a marginal regression approach is often employed to identify the potential risk factors of a failure. We consider...

Nonparametric estimation in mixture cure models with covariates

Nonparametric estimation methods for the cure rate and the distribution of the failure time of uncured subjects with covariates for censored survival data have attracted much attention in the last few years. T...

A Selective Overview of Statistical Methods for Identification of the Treatment-Sensitive Subsets of Patients

Identification of a subset of patients who may benefit from or be sensitive to a specific type of treatment has become a very important research topic in clinical trials and other types of clinical research. S...

An additive hazards frailty model with semi-varying coefficients

Proportional hazards frailty models have been extensively investigated and used to analyze clustered and recurrent failure times data. However, the proportional hazards assumption in the models may not always ...

Maximum likelihood estimation for length-biased and interval-censored data with a nonsusceptible fraction

Left-truncated data are often encountered in epidemiological cohort studies, where individuals are recruited according to a certain cross-sectional sampling criterion. Length-biased data, a special case of lef...

A support vector machine based semiparametric mixture cure model

The mixture cure model is an extension of standard survival models to analyze survival data with a cured fraction. Many developments in recent years focus on the latency part of the model to allow more flexibl...

Jointly modeling longitudinal proportional data and survival times with an application to the quality of life data in a breast cancer trial

Motivated by the joint analysis of longitudinal quality of life data and recurrence free survival times from a cancer clinical trial, we present in this paper two approaches to jointly model the longitudinal p...

Joint modeling of longitudinal proportional measurements and survival time with a cure fraction

In cancer clinical trials and other medical studies, both longitudinal measurements and data on a time to an event (survival time) are often collected from the same patients. Joint analyses of these data would...

Recent Development in the Joint Modeling of Longitudinal Quality of Life Measurements and Survival Data from Cancer Clinical Trials

In cancer clinical trials, longitudinal Quality of Life (QoL) measurements and survival time on a patient may be analyzed by joint models, which provide more efficient estimation than modeling QoL data and sur...

Integrating health-related quality of life findings from randomized clinical trials into practice: an international study of oncologists’ perspectives

Although health-related quality of life (HRQL) is increasingly assessed in randomized controlled trials (RCTs), HRQL findings are not always incorporated into clinical decision making. We examined the current ...

Semiparametric estimation methods for the accelerated failure time mixture cure model

This paper provides an overview of two semiparametric estimation methods recently proposed in the literature for the accelerated failure time mixture cure model. We prove that the two estimation methods are as...

An extended cure model and model selection

We propose a novel interpretation for a recently proposed Box–Cox transformation cure model, which leads to a natural extension of the cure model. Based on the extended model, we consider an important issue of...

Accelerated hazards mixture cure model

We propose a new cure model for survival data with a surviving or cure fraction. The new model is a mixture cure model where the covariate effects on the proportion of cure and the distribution of the failure ...

A marginal regression model for multivariate failure time data with a surviving fraction

A marginal regression approach for correlated censored survival data has become a widely used statistical method. Examples of this approach in survival analysis include from the early work by Wei et al. (J Am ...
