Abstract
We show that given a set of expectation values one can estimate the underlying probability distribution by use of ‘‘Schwinger-Dyson equations.’’ The method can be applied to obtain the evolution of coupling constants in Monte Carlo renormalization-group calculations. Some results for three- and four-dimensional scalar theory are presented briefly.Keywords
