Predictive modeling

Definition

Predictive modeling is a statistical technique used to predict future outcomes based on historical data by identifying patterns and trends. This process often involves algorithms that learn from data and can adapt as new information becomes available, making it a powerful tool in various fields, including science and industry. Its ability to generate forecasts can lead to better decision-making and resource allocation.
