Mosquito-borne pathogen transmission exhibits spatial-temporal variability caused by ecological interactions acting at different scales. We used local spatial statistics and geographically weighted regression (GWR) to determine the spatial pattern of malaria incidence and persistence in northeastern Venezuela. Seven to 11 hot spots of malaria transmission were detected by using local spatial st...
In Marine discussions, the study of sea surface temperature (SST) and study of its spatial relationships with other ocean parameters are of particular importance, in such a way that the accurate recognition of the SST relationships with other parameters allows the study of many ocean and atmospheric processes. Therefore, in this study, spatial relations modeling of SST with Surface Wind Speed (...
بطور متداول، برای درک ارتباطات فضایی بین متغیّرها محققان علوم محیطزیست و جغرافیا از الگوهایی چون رگرسیون حداقل مربعات معمولی (OLS) بهره میگیرند که دارای کاستیهای بسیاری در ارائهی نتایج فضایی بویژه در مقیاس محلی است. محققان در سالهای اخیر الگوی رگرسیونی وزنی جغرافیایی(GWR) به منظور درک روابط بین متغیّرهای فضایی در سطح محلی پیشنهاد دادهاند. در این تحقیق به منظور مقایسهی کارایی این الگوها، ...
Population projections at a small area level are sensitive to random departures in temporal trends of population change components. In order to have robust trends for the county level projections in Costa Rica, the team in charge of forecasting decided to determine county clusters based on the past trends. In this paper, we compare three descriptive techniques used to build space-time clusters ...
Geographically Weighted Regression (GWR) is used to analyze the spatial variability of the relationship between the surface and the subsurface (b horizon) soil metal concentration. We used publiclyavailable soil samples from provincial government websites in Canada. The correlation between the log of concentration levels of the two layers are 0.51 for As, 0.40 for Cd, 0.33 for Cr, 0.52 for Co, ...
Multicollinearities among the coefficients obtained from the method of geographically weighted regression have been identified in recent research. This is a serious issue that poses a critical challenge for the utility of the method as a tool to investigate multivariate relationships. The evidence regarding the ability of GWR to retrieve spatially varying processes remains mixed due to partial ...
Airbnb has been increasingly gaining popularity since 2008 due to its low prices and direct interactions with the local community. This paper employed a general linear model (GLM) and a geographically weighted regression (GWR) model to identify the key factors affecting Airbnb listing prices using data sets of 794 samples of Airbnb listings of business units in Metro Nashville, Tennessee. The r...
While recent developments have extended geographically weighted regression (GWR) in many directions, it is usually assumed that the relationships between dependent and independent variables are linear. In practice, however, often case nonlinearly associated. To address this issue, we propose a artificial neural network (GWANN). GWANN combines geographical weighting with networks, which able to ...
