Stochastic processes are mathematical models that analyze the evolution of systems influenced by randomness. They are crucial in finance for predicting market trends, in meteorology for weather forecasting, and in various scientific fields for simulating dynamic phenomena. Understanding these processes, including their stationarity and properties like the Markov property and ergodicity, is essential for managing uncertainty in natural and engineered systems.
