Complete consistency for the estimator of nonparametric regression model based on m-END errors

open access: yesOpen Mathematics, 2021
In this paper, we study the complete consistency for the estimator of nonparametric regression model based on m-END errors and obtain the convergence rates of the complete consistency under more general conditions.

A fundamental measure of treatment effect heterogeneity

open access: yesJournal of Causal Inference, 2021
The stratum-specific treatment effect function is a random variable giving the average treatment effect (ATE) for a randomly drawn stratum of potential confounders a clinician may use to assign treatment.

Identification of causal intervention effects under contagion

open access: yesJournal of Causal Inference, 2021
Defining and identifying causal intervention effects for transmissible infectious disease outcomes is challenging because a treatment – such as a vaccine – given to one individual may affect the infection outcomes of others. Epidemiologists have proposed

Explaining predictive models using Shapley values and non-parametric vine copulas

open access: yesDependence Modeling, 2021
In this paper the goal is to explain predictions from complex machine learning models. One method that has become very popular during the last few years is Shapley values.

Robust estimation for varying coefficient partially functional linear regression models based on exponential squared loss function

open access: yesOpen Mathematics, 2022
In this article, we present a new robust estimation procedure based on the exponential squared loss function for varying coefficient partially functional linear regression models, where the slope function and nonparametric coefficients are approximated ...

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.

Incremental intervention effects in studies with dropout and many timepoints#

open access: yesJournal of Causal Inference, 2021
Modern longitudinal studies collect feature data at many timepoints, often of the same order of sample size. Such studies are typically affected by dropout and positivity violations.

Large deviations for exchangeable observations with applications

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2004, Issue 55, Page 2947-2958, 2004., 2004
We first prove some large deviation results for a mixture of i.i.d. random variables. Compared with most of the known results in the literature, our results are built on relaxing some restrictive conditions that may not be easy to be checked in certain typical cases.

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 ...

Strong Consistency of Estimators for Heteroscedastic Partly Linear Regression Model under Dependent Samples

open access: yesInternational Journal of Stochastic Analysis, Volume 15, Issue 3, Page 207-219, 2002., 2002
In this paper we are concerned with the heteroscedastic regression model yi = xiβ + g(ti) + σiei, 1 ≤ i ≤ n under correlated errors ei, where it is assumed that σi2=f(ui), the design points (xi, ti, ui) are known and nonrandom, and g and f are unknown functions. The interest lies in the slope parameter β.
