A4.1 Some auxiliary information on methods and algorithms of statistical processing of non-quantitative characteristics
In the study of determinant characteristics, we are faced with the need to statistically analyse multidimensional random variables X of so-called mixed nature. We are talking about situations characterized by the fact that among the vector components X can be both quantitative and qualitative (rank) and classification (nominal) characteristics.
