Redundancy and relevancy of analytical results in multielement analysis.
From the point of view of the information theory, the term relevancy is actual only in the case of multielement determinations, because the information of one component determination is basically relevant. In the multicomponent determination the surplus of information, the s.c. redundancy, is given on the one hand by the relation between the information parameters of the analytical order and the equivalent parameters derived from the experimental data. On the other hand, the information from the individual terms of determined information parameters also have individual degrees of redundancy. But the given redundancy, the weight of information, is not necessarily always useful. The main problem is the correct and true determination of the given redundancy and following degree of relevancy.
