We prove that Bayesian updating for population mean vectors of multivariate normal distributions can be expressed as an affine symplectic transformation on a phase space with the canonical symplectic structure. %K Bayesian Inference %K Hamiltonian %K Symplectic %K Canonical Transformation %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=95440
