Regional transfer-learning framework for maize-yield estimation in Zimbabwe: Supplementary data, model outputs and sensitivity-analysis results

This dataset contains machine-readable supplementary outputs supporting a PhD thesis on regional transfer learning for annual national maize-yield estimation in Zimbabwe. The files include final SPAM2020 model-comparison results, SPAM2010 sensitivity results, combined test-performance metrics and matched-model stability outputs. Zimbabwe was treated as the target domain, while Malawi, Mozambique, South Africa and Zambia provided empirical source-domain observations. The archive also includes documentation describing the files, modelling terminology, principal results and reproducibility procedures.
