A single-index model with multiple-links. [PDF]

open access: yesJ 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]

open access: yesJournal of the American Statistical Association, 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]

open access: yesElectronic Journal of Statistics, 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.

Understanding Implicit Regularization in Over-Parameterized Single Index Model. [PDF]

open access: yesJ 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.

Bayesian composite quantile regression for the single-index model. [PDF]

open access: yesPLoS 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.

Single-Index Model Tree

open access: yesIEEE 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 ...

Using a monotone single-index model to stabilize the propensity score in missing data problems and causal inference. [PDF]

open access: yesStat Med, 2019
The augmented inverse weighting method is one of the most popular methods for estimating the mean of the response in causal inference and missing data problems. An important component of this method is the propensity score.

Robust Estimation for the Single Index Model Using Pseudodistances. [PDF]

open access: yesEntropy (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

open access: yesMathematics, 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 ...
