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

  title={Asymptotic Properties of the Maximum Smoothed Partial Likelihood Estimator in the Change-Plane Cox Model},
  author={Shota Takeishi},
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.
Subgroup detection and sample size calculation with proportional hazards regression for survival data
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.
Multithreshold change plane model: Estimation theory and applications in subgroup identification
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.
The Change-Plane Cox Model.
A projection pursuit technique in survival analysis for finding lower-dimensional projections that exhibit differentiated survival outcome and a potential framework for principled subgroup discovery is proposed.

A new algorithm to ease the computation of the threshold boundary is put forward, the asymptotics for the least squares estimator are developed, and a new score-type test is proposed to test for the existence of threshold effects.
Sample Splitting and Threshold Estimation
Threshold models have a wide variety of applications in economics. Direct applications include models of separating and multiple equilibria. Other applications include empirical sample splitting when
