Abstract

The application of multivariate procedures, from the generalized associations matrix of index a, increases the variability of the first factorial axes, allowing the detection of classifications, starting from the representation in a factorial space of reduced dimension. The MINDAN procedure, obtained from the correlations among the defined associations, defines a single variable that allows classification of the objects. 1 Introduction The Net of Surveillance of Atmospheric Contamination is designed for the diagnosis of the quality of the air in the populations with influence of industrial activity. For their application in a certain geographical area, they settled 11 stations whose sensors determine daily, in real time, the mea
