The use of a mathematical model with different values as variables in order to determine the likelihood of a particular outcome. A simulation is run many times (often thousands) in order to find the most likely outcome. Running simulations is important for analysts who, for example, wish to predict a security's future price movements.


To create an artificial environment or circumstance that closely resembles reality so that people may test their predictions about behavior or practice their skills. One may purchase simulation software to help new real estate agents learn how to interact with buyers and sellers or house-flipping simulation software to learn the tricks and perils of that process.
