M4 Forecasting Competition Series Metadata

If you're building a forecasting model, you need to know what you're predicting. This is a reference guide to 100,000 time series used in a major forecasting competition. It tells you whether each series is about demographics, finance, or something else, whether it's recorded yearly or hourly, how far into the future you need to predict, and when the data starts. It's useful if you want to test your forecasting approach on diverse, real-world data or understand what kinds of forecasting problems exist in practice.
