Forecasting vs simulation
WebSep 1, 2013 · Principles of Modeling and Simulation: A Multidisciplinary Approach is the first book to provide an introduction to modeling and simulation techniques across diverse areas of study. WebIn general, computing a (point) forecast involves computing a conditional expectation (the expected value of a process in the future, conditional on information known up to today). Monte Carlo methods are used to approximate expectations, so they may be used for models where the forecast expectation can't be computed analytically.
