Monte Carlo Simulations

Definition

Monte Carlo simulations are mathematical techniques used to estimate the possible outcomes of uncertain events by generating random samples from a defined probability distribution. This method allows analysts to assess risk and make informed decisions by simulating a wide range of scenarios, thus providing insights into the potential variability and impact of different factors on a given outcome.
