Asymptotic Behavior of a Nonparametric Estimator of the Renewal Function for Random Fields

open access: yesMathematics, 2023
In this paper, we study the asymptotic normality of a nonparametric estimator of the renewal function associated with a sequence of absolutely continuous nonnegative two-dimensional random fields.

On properties of local additive estimation based on the smooth backfitting estimator. [PDF]

open access: yes, 2008
We study properties of local additive estimation based on the smooth backfitting estimator by Mammen, Linton and Nielsen (1999). The local additive estimator defined as a restricted additive estimator and thus inherits locally properties of additive ...

All models are wrong, but which are useful? Comparing parametric and nonparametric estimation of causal effects in finite samples

open access: yesJournal of Causal Inference, 2023
There is a long-standing debate in the statistical, epidemiological, and econometric fields as to whether nonparametric estimation that uses machine learning in model fitting confers any meaningful advantage over simpler, parametric approaches in finite ...

Estimation Curve of Mixed Spline Truncated and Fourier Series Estimator for Geographically Weighted Nonparametric Regression

open access: yesMathematics, 2022
Geographically Weighted Regression (GWR) is the development of multiple linear regression models used in spatial data. The assumption of spatial heterogeneity results in each location having different characteristics and allows the relationships between ...

A COMPARISON OF NONPARAMETRIC ESTIMATORS FOR LENGTH DISTRIBUTION IN LINE SEGMENT PROCESSES

open access: yesImage Analysis and Stereology, 2019
We study nonparametric estimation of the length distribution for stationary line segment processes in the d-dimensional Euclidean space. Several methods have been proposed in the literature. We review different approaches (Horvitz-Thompson type estimator,

Nonparametric Range-Based Double Smoothing Spot Volatility Estimation for Diffusion Models

open access: yesComplexity, 2020
We consider nonparametric spot volatility estimation for diffusion models with discrete high frequency observations. Our estimator is carried out in two steps.

COMPARING GAUSSIAN AND EPANECHNIKOV KERNEL OF NONPARAMETRIC REGRESSION IN FORECASTING ISSI (INDONESIA SHARIA STOCK INDEX)

open access: yesBarekeng, 2022
ISSI reflects the movement of sharia stock prices as a whole. It is necessary to forecast the share price to help investors determine whether the shares should be sold, bought, or retained. This study aims to predict the value of ISSI using nonparametric

On Nonparametric Hazard Estimation [PDF]

open access: yesJournal of Biometrics & Biostatistics, 2015
The Nelson-Aalen estimator provides the basis for the ubiquitous Kaplan-Meier estimator, and therefore is an essential tool for nonparametric survival analysis. This article reviews martingale theory and its role in demonstrating that the Nelson-Aalen estimator is uniformly consistent for estimating the cumulative hazard function for right-censored ...
