Reproducible analysis code for Physical Activity and Learning Satisfaction in Children: A Cross-Country Analysis Using Global Survey Data

Résumé fourni par la source

This software and reproducibility package implements the definitive cross-country analysis of physical activity and learning satisfaction using Wave 3 data from the International Survey of Children’s Well-Being (ISCWeB / Children’s Worlds). It includes code for country/item eligibility audits, structural-missingness harmonization, weighted school-grouped LASSO cross-validation with the 1-SE rule, case-weighted WLS with country-school clustered standard errors, country fixed-effects and heterogeneity analyses, exploratory country-specific models, and a separately eligible indirect-effect analysis through perceived learning progress. Aggregate reference outputs and a detailed codebook are included. Original and derived row-level ISCWeB microdata are not redistributed.
