Abstract

Accurate sales forecasting is vital for business planning, inventory control, and promotions. While Ridge regression and XGBoost have been widely applied separately, this study proposes a novel hybrid combining their strengths in linear regularization and nonlinear boosted trees. Using the Rossmann Store Sales dataset (over one million transactions, 1,115 stores), we applied systematic preprocessing, advanced feature engineering (lags, rolling statistics, expanding means, cyclical and leave-one-out encoding), and Optuna-based hyperparameter tuning with a time-based split. The hybrid was evaluated in three stages: baseline (R2 = 0.53), tuned (R2 = 0.79), and engineered+tuned (R2 = 0.99). Results show the proposed Ridge–XGBoost framework significantly outperforms individual models and benchmarks, offering a scalable and interpretable solution for retail demand forecasting.
