Title R script for INLA modeling
Downloaded 10 times
Description Takes in data in cpn.csv, grid.csv, and mpios.shp and produces map.graph for defining neighboring spatial units, runs and prints spatially explicit binomial models of Table 2. Saves results as d_models3.Rdata

Title R script to make predictions based on INLA modeling
Downloaded 10 times
Description Obtains predictions from models of Table 2, runs AUC analyses of pixel predictions, and prints predictions of model without predictor (no influence of distance to projects), model using the nearest project as random effect along with influence of distance to projects (pred2), and the model using municipality intercepts as random effects along with with influence of distance to projects (pred6). The latter is the best-fit model. The script also saves the three-model results as GeoTIFF rasters, the best model is listed as best_auc_hr.tif. NOTE: This R script must run after d2pro3_hires.R, or after loading d_models3.Rdata

Title R script to plot logistic model
Downloaded 6 times
Description Loads the data generated by script d2pro3_hires.R and generates a decay function plot based on the posteriors of the relationship between probability of finding coca by pixel and the log10 distance to the nearest development project. It also plots the observations. NOTE: this script must run after d2pro3_hires.R, or after loading d_models3.Rdata
