Stochastic modeling

Definition

Stochastic modeling is a mathematical approach used to predict future outcomes based on random variables and inherent uncertainties. It incorporates the randomness present in real-world systems, making it particularly useful in fields like energy management and forecasting. This technique allows for better decision-making by providing a range of possible scenarios rather than a single deterministic outcome.
