A forecast is a prediction or estimate of future events, conditions, or outcomes based on the analysis of available data and trends. It is commonly used in various fields, including finance, meteorology, economics, and business, to anticipate changes and make informed decisions. Forecasts can be qualitative or quantitative, often involving statistical techniques, models, or expert judgment to project future scenarios. The accuracy of a forecast can depend on the quality of the data and the assumptions made during the forecasting process.
