Proyectos de código
Cada artículo de investigación tiene su propio pequeño proyecto de código. Los scripts cargan datos públicos, hacen el análisis y guardan exactamente las gráficas y tablas que usa el artículo, para que cualquiera pueda verificar o reproducir las cifras.El código y sus descripciones están en inglés.
Cada proyecto está en su propia carpeta, projects/<nombre-del-artículo>/, con las mismas partes:
