Predictive Modeling

Definition

Predictive modeling is a statistical technique that uses historical data and algorithms to identify patterns and make predictions about future outcomes. This method is vital in various fields, including Systems Biology, where it helps in understanding complex biological systems by forecasting responses to changes and interventions. By leveraging data, predictive modeling aids in drug discovery, development, and understanding complex diseases, enhancing our ability to anticipate effects before they occur.
