  journal={arXiv: Methodology},
A novel functional additive model is proposed which is uniquely modified and constrained to model nonlinear interactions between a treatment indicator and a potentially large number of functional/scalar covariates. We generalize functional additive regression models by incorporating treatment-specific components into additive effect components. A structural constraint is imposed on the treatment-specific components, to give a class of orthogonal main and interaction effect additive models. If…

A Simple Method for Estimating Interactions Between a Treatment and a Large Number of Covariates
It is shown that coupled with an efficiency augmentation procedure, this method produces clinically meaningful estimators in a variety of settings and can be useful for practicing personalized medicine: determining from a large set of biomarkers, the subset of patients that can potentially benefit from a treatment.
Flexible functional regression methods for estimating individualized treatment rules
This work combines the flexibility of functional additive regression models with Q-learning or A-learning in order to obtain treatment decision rules and proposes two approaches for using functional data to select an optimal treatment that address some of the shortcomings of previously developed methods.
Sparse additive models
An algorithm for fitting the models is derived that is practical and effective even when the number of covariates is larger than the sample size, and empirical results show that they can be effective in fitting sparse non‐parametric models in high dimensional data.
High-Dimensional Inference for Personalized Treatment Decision.
An asymptotically unbiased estimator based on Lasso solution for the interaction coefficients is proposed and the limiting distribution of the estimator is derived when baseline function of the regression model is unknown and possibly misspecified.
Constructing treatment decision rules based on scalar and functional predictors when moderators of treatment effect are unknown
This work presents an approach that identifies covariates associated with differential treatment effect and estimates a treatment decision rule based on these covariates and focuses on settings where there is a potentially large collection of candidate biomarkers consisting of both scalar and functional data.
Functional additive regression
Functional Additive Regression uses a penalized least squares optimization approach to efficiently deal with high-dimensional problems involving a large number of functional predictors and can significantly outperform competing methods.
Generalized Additive Models
Likelihood-based regression models such as the normal linear regression model and the linear logistic model, assume a linear (or some other parametric) form for the covariates Xlt X2, ■•-, Xp. We
Treatment decisions based on scalar and functional baseline covariates
This work proposes an approach that uses baseline covariates, both scalars and functions, to aid in the selection of an optimal treatment and can be viewed as an extension of “advantage learning” to include both scalar and functional covariates.
Variable Selection for Qualitative Interactions in Personalized Medicine While Controlling the Family-Wise Error Rate
This article proposes a new technique designed specifically to find interaction variables among a large set of variables while still controlling for the number of false discoveries and compares this new method against standard qualitative interaction tests using simulations.
On sparse representation for optimal individualized treatment selection with penalized outcome weighted learning
This article develops a variable selection method based on penalized outcome weighted learning through which an optimal treatment rule is considered as a classification problem where each subject is weighted proportional to his or her clinical outcome.
