# Asymptotic Properties of the Maximum Smoothed Partial Likelihood Estimator in the Change-Plane Cox Model

@inproceedings{Takeishi2021AsymptoticPO, title={Asymptotic Properties of the Maximum Smoothed Partial Likelihood Estimator in the Change-Plane Cox Model}, author={Shota Takeishi}, year={2021} }

The change-plane Cox model is a popular tool for the subgroup analysis of survival data. Despite the rich literature on this model, there has been limited investigation into the asymptotic properties of the estimators of the ﬁnite-dimensional parameter. Particularly, the convergence rate, not to mention the asymptotic distribution, remains an unsolved problem for the general model where classiﬁcation is based on multiple covariates. To bridge this theoretical gap, this study proposes a maximum…

Subgroup analysis in the heterogeneous Cox model

A data driven subgroup analysis procedure for the heterogeneous Cox model is proposed by constructing a pairwise fusion penalized partial likelihood-based objective function that can determine the number of subgroups, identify the group structure, and estimate the treatment effect simultaneously and automatically.

A score-type test for detecting the existence of the subgroup is developed, which is doubly robust against misspecification of the baseline effect model or the propensity score but not both under mild assumptions for censoring.

A novel two-stage estimation approach to determine the number of subgroups, the location of thresholds, and all other regression parameters is contributed to a multithreshold change plane regression model which naturally partitions the observed subjects into subgroups with different covariate effects.
