It is proved that for any two positive deΓΏnite Hermitian m Γ m matrices I and V subject to I ΒΏV -1 there exists an m-variate random vector X with V as its covariance matrix and I its matrix of Fisher information.
General model-independent relationships among radial expectation values of the one-particle densities in position and momentum spaces for any quantum-mechanical system are obtained. They are derived from the Stam uncertainty principle and the recently reported lower bounds to the Fisher information
