A single-index model with multiple-links. [PDF]
J Stat Plan Inference, 2020 In a regression model for treatment outcome in a randomized clinical trial, a treatment effect modifier is a covariate that has an interaction with the treatment variable, implying that the treatment efficacies vary across values of such a covariate.

A Functional Varying-Coefficient Single-Index Model for Functional Response Data. [PDF]
J Am Stat Assoc, 2017 Motivated by the analysis of imaging data, we propose a novel functional varying-coefficient single-index model (FVCSIM) to carry out the regression analysis of functional response data on a set of covariates of interest.

Semiparametric Single-Index Model for Estimating Optimal Individualized Treatment Strategy. [PDF]
Electron J Stat, 2017 Different from the standard treatment discovery framework which is used for finding single treatments for a homogenous group of patients, personalized medicine involves finding therapies that are tailored to each individual in a heterogeneous group.

Robust Estimation for the Single Index Model Using Pseudodistances. [PDF]
Entropy (Basel), 2018 For portfolios with a large number of assets, the single index model allows for expressing the large number of covariances between individual asset returns through a significantly smaller number of parameters.

On a Low-Rank Matrix Single-Index Model
Mathematics, 2023 In this paper, we conduct a theoretical examination of a low-rank matrix single-index model. This model has recently been introduced in the field of biostatistics, but its theoretical properties for jointly estimating the link function and the ...

Understanding Implicit Regularization in Over-Parameterized Single Index Model. [PDF]
J Am Stat Assoc, 2023 In this article, we leverage over-parameterization to design regularization-free algorithms for the high-dimensional single index model and provide theoretical guarantees for the induced implicit regularization phenomenon.

IEEE Transactions on Knowledge and Data Engineering, 2023 In this paper, a novel single-index model tree (SIMTree) is proposed. It adopts the recursive partitioning strategy and each data segment is modeled by a single-index model (SIM), which is a flexible extension of linear regression with non-parametric ...

Bayesian composite quantile regression for the single-index model. [PDF]
PLoS ONE, 2023 By using a Gaussian process prior and a location-scale mixture representation of the asymmetric Laplace distribution, we develop a Bayesian analysis for the composite quantile single-index regression model.

Variable selection for the single-index model [PDF]
Biometrika, 2007 We consider variable selection in the single-index model. We prove that the popular leave-m-out crossvalidation method has different behaviour in the single-index model from that in linear regression models or nonparametric regression models. A new consistent variable selection method, called separated crossvalidation, is proposed.
