title: Statistical assessment of the value of numerical evidence.
abstract: Statistical parameter V measuring the value of numerical evidence was introduced. It is a decisional parameter and it changes between 0 and 1. Its definition takes into account statistical properties of the general population and sources investigated, as well as the operating characteristic function of the test used. It was concluded that the value of evidence increases contrary to the value of the quotient of determinants of variance--covariance matrices of the source population and general population. A method was developed to choose attributes of the investigated material to satisfy best possible results of the identification.
