A forecast is a prediction or estimation of future events or conditions, based on the analysis of current and historical data. It is commonly used in various fields such as meteorology, economics, finance, and business to anticipate outcomes and trends. In meteorology, for instance, weather forecasts predict future weather conditions based on atmospheric data. In business, forecasts help organizations estimate future sales, revenue, and market trends to guide decision-making and strategic planning. Effective forecasting relies on statistical methods, models, and algorithms to analyze patterns and inform predictions, enabling individuals and organizations to plan proactively and mitigate risks associated with uncertainty.
