An algorithm to generate samples with approximate first-, second-, and third-order moments is presented extending the Cholesky matrix decomposition to a Cholesky tensor decomposition of an arbitrary order. The tensor decomposition of the first-, second-, and third-order objective moments...

Leo Breiman (Breiman et al., 1984, 1998) was a statistician who was fond of practical applications, and this led him to develop several original studies. Based on the work begun by Friedman (1977), he developed a very accurate classification system, without the need for statistical assumptions,...

This research aims to investigate, through simulation models, how the interaction among agents in an artificial stock market can affect the dynamics of asset prices. Thus, the study follows a different methodology for the analysis of prices by exploring the simulation of agents' behavior in an...
