The confusion probability distribution in interferometer observations is derived. It is shown that the form of the distribution depends on the correlation between fringe visibilities V and flux densities S of radio sources. Because the V-S correlation depends on the universe model, the evolution of radio source dimensions, and the evolution of the radio luminosity function, the statistical VLBI observations give a new cosmological test to analyse different universe models and evolution models.
