摘要:The study of a game could be modelled assuming that only some hands are watched. Then the tree game must be estimated making use of sampling information. It happens the same when we get information about the behaviour of the decisions taken by individual sampled by a tree of theory decision. By considering a probabilistic measurement of cross-section samples we might get an estimatation of the associated tree. This is the problem analysed on this working paper. Some experimental results obtained by using the Recocido Simulado illustrate the procedure. The role at the study of economic and trading models is discussed.
