A note on promotion time cure models with a new biological consideration

TL;DR

This paper introduces a generalized promotion time cure model that incorporates biological considerations, enhancing the modeling of heterogeneous survival data and complex reliability systems.

Contribution

The paper presents a novel, flexible promotion time cure model that accounts for biological factors and heterogeneity in survival and reliability data.

Findings

Model effectively captures intra-sample heterogeneity.

Suitable for complex systems with multiple subsystems.

Enhances biological relevance in survival analysis.

Abstract

We introduce a generalized promotion time cure model motivated by a new biological consideration. The new approach is flexible to model heterogeneous survival data, in particular for addressing intra-sample heterogeneity. We also indicate that the new approach is suited to model a series or parallel system consisting of multiple subsystems in reliability analysis.
