fs-food-security-income Code and data to reproduce the income-group analyses for the manuscript. What this repo contains data/ step_1_food_security_income.xlsx — Step 1 (stratified bivariate models by income group) step_2_food_security_income.xlsx — Step 2 (hierarchical/mixed-effects panel models) step_3_food_security_income.xlsx — Step 3 (mixed-effects moderator screening) src/ Main Analysis.R — main analysis pipeline (requires the master input dataset; update the input path at the top of the script). Plots.R — figure generation from the data/step_* files (update the read_excel() paths at the top to point to data/). Quick start (R) Open R in the repository root. Install packages (if needed): readxl, dplyr, tidyr, ggplot2, scales, gridExtra, grid, plus modeling packages used in the pipeline (MASS, sandwich, lmtest, lme4, glmmTMB). Reproduce figures: Edit the three read_excel() lines at the top of src/Plots.R to use data/step_*.xlsx.
