Feature-Engineered Daily Dataset (2015–2025)

This file contains a feature-engineered daily dataset covering 2015 to 2025. It includes a wide set of derived variables such as temporal features, lagged values, rolling statistics, volatility measures, entropy metrics, jump indicators, and fractal-dimension estimates, created from multiple public data sources. All features are aligned by date and preserved without interpolation except for annual values that are broadcast to a daily frequency. This dataset is intended for reusable modeling, forecasting, and exploratory data analysis workflows.
