Optimal weight settings in locally weighted regression: A guidance through cross-validation approach
Locally weighted regression is a powerful tool that allows the estimation of different sets of coefficients for each location in the underlying data, challenging the assumption of stationary regression coefficients across a study region. The accuracy of LWR largely depends on how a researcher …

The Image from the Road: Towards Mapping the Phenomenological
… representations are made using GIS and locally weighted regression of the experiential phenomenon of structural density along roadways in Faytteville, Arkanasas. An alternative method of characterizing the city, one that accounts for the phenomenological as experienced from a human field …

Nonparametric function smoothing: fiducial inference of free knot splines and ecological applications
… statisticians. Classic techniques such as locally weighted regression and smoothing splines are being used in a variety of circumstances to address questions at the forefront of ecological theory. We first examine an ecological threshold problem and define a threshold as where the …

Use of data-driven models to improve prediction of physically based groundwater models
… techniques, instance-based weighting (IBW), locally weighted regression (\textit{loess}), decision trees (DT), artificial neural networks (ANN) and support vector regression (SVR) are employed to construct the DDMs, and their performance of enhancing the prediction of the PBM is compared. …

Vertex-Based Analysis of Cerebral Blood Flow and Fractional Amplitude of Low-Frequency Fluctuations (CBF-fALFF) Coupling in Moderate-to-Severe Traumatic Brain Injury During the First Year Post-Injury
… was estimated by association (measured by regression or correlation coefficients) between CBF and fALFF values across the whole hemisphere. In addition, vertex-wise regional coupling values were calculated using locally weighted regression between fALFF and CBF. The coupling calculated on a …

Methodological advances in benefit transfer and hedonic analysis
… environmental policy changes by adopting locally weighted regression (LWR) technique in an environmental valuation context, the second chapter combines the output from traditional hedonic regression and matching estimators and provides guidance on the choice of model with low risk of bias …
