On the spatial distance between training and validation data in model evaluation: data, codes, and reproduction workflow

The files "<b>GenerateSimData.pdf</b>", "<b>SimulationAnalysis.pdf</b>", and "<b>CaseStudy.pdf</b>" are compiled R Markdown documents that demonstrate and reproduce the workflows for generating simulated data, conducting simulation analysis, and performing a case study, respectively. Each PDF includes the <b>R code and its direct output </b>(e.g., figures and results).<br>To reproduce these workflows in your environment, the "<b>Workflow_reproduction</b>" ZIP file contains all necessary R Markdown files, code with comments, and accompanying datasets. Specifically:<br>"<b>GenerateSimData.Rmd</b>" reproduces the workflow for generating simulated data.<br>"<b>SimulationAnalysis.Rmd</b>" reproduces the simulation analysis workflow.<br>"<b>casestudy.Rmd</b>" reproduces the case study analysis.<br>To run a specific part of the workflow, please download and unzip the "<b>Workflow_reproduction.zip</b>" file, then open the corresponding ".Rmd" file in RStudio and click the green "<b>Run Current Chunk</b>" arrow icon to execute each code chunk interactively.<br>If you would like to reproduce the workflow in the original environment entirely, we also provide the following resources:<br>The "<b>Data_file.zip</b>" file contains the response variables, explanatory variables, and simulated data.<br>The "<b>Origin_code.zip</b>" file contains the origin code for the manuscript:<br>"<b>spatial random sim.R</b>": The code for generating the simulated data.<br>"<b>sim case.R</b>": The code for simulation analysis.<br>"<b>compute_sliding_window_metrics.R</b>": The code for the moving distance validation model.<br>"<b>fun_spatially_weighted_validation.R</b>": The code for calculating the spatially weighted indicators.<br>"<b>Modelling.R</b>": The code for the case study.To run the entire workflow using the code from "Origin_code.zip," please download both "Origin_Code.zip" and "Data_file.zip." After unzipping "Origin_code.zip," extract the data of "Data_file.zip" into the unzipped "Origin_Code" folder, then run the workflow.
