stochastic simulation
A stochastic simulation is a simulation that traces the evolution of variables that can change stochastically (randomly) with certain probabilities.〔DLOUHÝ, M.; FÁBRY, J.; KUNCOVÁ, M.. Simulace pro ekonomy. Praha : VŠE, 2005.〕
With a stochastic model we create a projection which is based on a set of random values. Outputs are recorded and the projection is repeated with a new set of random values of the variables. These steps are repeated until a sufficient amount of data is gathered. In the end, the distribution of the outputs shows the most probable estimates as well as a frame of expectations regarding what ranges of values the variables are more or less likely to fall in.〔
==Etymology==
''Stochastic'' originally meant "pertaining to conjecture"; from Greek stokhastikos "able to guess, conjecturing": from stokhazesthai "guess"; from stokhos "a guess, aim, target, mark". The sense of "randomly determined" was first recorded in 1934, from German Stochastik.〔stochastic. (n.d.). Online Etymology Dictionary. Retrieved January 23, 2014, from Dictionary.com website: http://dictionary.reference.com/browse/stochastic〕
