Stochastic modeling is a mathematical tool for analyzing systems affected by randomness, crucial in finance, physics, and biology. It uses probabilistic methods to predict complex system behaviors, employing stochastic processes like Geometric Brownian Motion and Stochastic Differential Equations. These models and processes are vital for decision-making in uncertain conditions and have practical applications in financial analysis, environmental science, and epidemiology.
