On the integration of decision trees with mixture cure model

W Aselisewine, S Pal - Statistics in Medicine, 2023 - Wiley Online Library
The mixture cure model is widely used to analyze survival data in the presence of a cured
subgroup. Standard logistic regression‐based approaches to model the incidence may lead …

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

S Pal, Y Peng, W Aselisewine - Computational Statistics, 2024 - Springer
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 …

On the parameter estimation of Box‐Cox transformation cure model

S Pal, S Roy - Statistics in Medicine, 2023 - Wiley Online Library
We propose an improved estimation method for the Box‐Cox transformation (BCT) cure rate
model parameters. Specifically, we propose a generic maximum likelihood estimation …

On the estimation of destructive cure rate model: a new study with exponentially weighted Poisson competing risks

S Pal, S Roy - Statistica Neerlandica, 2021 - Wiley Online Library
A new estimation method is proposed founded upon a nonlinear conjugate gradient‐type
algorithm having an efficient line search technique for cure rate models with competing risks …

A stochastic version of the EM algorithm for mixture cure model with exponentiated Weibull family of lifetimes

S Pal, S Barui, K Davies, N Mishra - Journal of Statistical Theory and …, 2022 - Springer
In this paper, we propose a stochastic approximation to the well-studied expectation–
maximization (EM) algorithm for finding the maximum likelihood (ML)-type estimates in …

On the estimation of interval censored destructive negative binomial cure model

J Treszoks, S Pal - Statistics in Medicine, 2023 - Wiley Online Library
In this article, a competitive risk survival model is considered in which the initial number of
risks, assumed to follow a negative binomial distribution, is subject to a destructive …

On a reparameterization of a flexible family of cure models

FS Milienos - Statistics in Medicine, 2022 - Wiley Online Library
The existence of items not susceptible to the event of interest is of both theoretical and
practical importance. Although researchers may provide, for example, biological, medical, or …

A simplified stochastic EM algorithm for cure rate model with negative binomial competing risks: an application to breast cancer data

S Pal - Statistics in Medicine, 2021 - Wiley Online Library
In this article, a long‐term survival model under competing risks is considered. The
unobserved number of competing risks is assumed to follow a negative binomial distribution …

A destructive shifted Poisson cure model for interval censored data and an efficient estimation algorithm

J Treszoks, S Pal - Communications in Statistics-Simulation and …, 2024 - Taylor & Francis
In this paper, we consider a competitive risk scenario in which the initial number of
competing risks, assumed to follow a shifted Poisson distribution, is subject to a destructive …
