# Stochastic Modeling

## What is Stochastic Modeling?

Stochastic modeling is a statistical method that is used to analyze systems that are subject to randomness or uncertainty. It involves the use of mathematical models to represent the probability of different outcomes or events occurring.

Stochastic modeling is often used in a variety of fields, including finance, insurance, engineering, and natural sciences. It can be used to forecast future events, assess risk, optimize decision making, and analyze the behavior of complex systems.

In a stochastic model, random variables are used to represent uncertain quantities. These variables can be continuous (e.g. a continuous range of values) or discrete (e.g. a set of distinct values). Stochastic models often involve the use of probability distributions, which describe the likelihood of different outcomes occurring.

Some examples of stochastic models include:

• Monte Carlo simulations: used to model systems with a large number of variables and to estimate the probability of different outcomes occurring
• Markov processes: used to model systems that change over time and depend on the current state of the system, rather than the history of the system
• Queueing theory: used to model the flow of customers or other entities through a system, such as a call center or a supply chain

Stochastic modeling allows organizations to better understand and predict the behavior of such systems and to make more informed decisions.
