Semiparametric discovery and estimation of interaction in mixed exposures using stochastic interventions [PDF]

open access: yesJournal of Causal Inference
Understanding the complex interactions among multiple environmental exposures is critical for assessing their combined impact on health outcomes. This study introduces InterXshift, a novel semiparametric method that provides a nonparametric definition of

Application of one-step method to parameter estimation in ODE models. [PDF]

open access: yesStat Neerl, 2018
In this paper, we study application of Le Cam's one‐step method to parameter estimation in ordinary differential equation models. This computationally simple technique can serve as an alternative to numerical evaluation of the popular non‐linear least squares estimator, which typically requires the use of a multistep iterative algorithm and repetitive ...

Asymptotic normality of the relative error regression function estimator for censored and time series data

open access: yesDependence Modeling, 2021
Consider a survival time study, where a sequence of possibly censored failure times is observed with d-dimensional covariate The main goal of this article is to establish the asymptotic normality of the kernel estimator of the relative error regression ...

Heterogeneous interventional effects with multiple mediators: Semiparametric and nonparametric approaches

open access: yesJournal of Causal Inference, 2023
We propose semiparametric and nonparametric methods to estimate conditional interventional indirect effects in the setting of two discrete mediators whose causal ordering is unknown. Average interventional indirect effects have been shown to decompose an

Multivariate variable selection by means of null-beamforming

open access: yes, 2021
This article aims to use beamforming, a covariate-assisted data projection method to solve the problem of variable selection for multivariate random-effects regression models. The new approach attempts to explore the covariance structure in the data with

Nonparametric inference for interventional effects with multiple mediators

open access: yesJournal of Causal Inference, 2021
Understanding the pathways whereby an intervention has an effect on an outcome is a common scientific goal. A rich body of literature provides various decompositions of the total intervention effect into pathway-specific effects.

SPADES AND MIXTURE MODELS [PDF]

open access: yes, 2009
This paper studies sparse density estimation via l1 penalization (SPADES). We focus on estimation in high-dimensional mixture models and nonparametric adaptive den- sity estimation.
