Script and Dataset for Scale-dependent Environmental Pathways Shape Global Language Diversity

This dataset contains the code and input files required to reproduce the geographically weighted path analysis used in the world language study. The workflow fits stationary and geographically weighted path models across selected spatial resolutions and language-richness data sources. The main analysis script reads the input manifest, loads the corresponding equal-area grids and predictor tables, selects geodesic GWR bandwidths using information criteria, fits the path models, extracts coefficients and diagnostics, and writes reproducible tables and spatial outputs.
