Abstract
It is shown that quantum dynamics is equivalent to a stochastic proces s in phase space. The process is described by normalized but not neces sarily positive probability distributions (''pseudoprobabilities''). E volution of the simultaneous probability distribution of moment um and coordinate exactly coincides with the dynamics of the Wigner function of a quantum system.
