Forecasting

Forecasting is the process of making predictions about the future based on past and present data and analysis of trends. It involves using various statistical methods, models, and expert opinions to anticipate events, demands, or outcomes. The goal is to provide an informed estimate of what might happen, aiding in decision-making, planning, and risk management. Forecasts are often used in business, economics, meteorology, and various scientific fields, varying in complexity and accuracy depending on the data quality, methodologies employed, and the inherent uncertainty of the future. The effectiveness of a forecast is evaluated by how closely it aligns with the actual outcome, often assessed using metrics like Mean Absolute Error or Root Mean Squared Error.
