Scientific paper

A multidimensional statistical analysis of the integral properties of normal galaxies was performed, by applying principal component analysis to radio and optical data from several large catalogues. It is found that the statistical behavior of these galaxies is very similar, despite the different methods used to calculate their physical magnitudes. In all cases, the observational material could be described in terms of two uncorrelated variables, (Brosche, 1973). The global differences were found to result in part from errors in the adopted distances; this parameter must be carefully determined, since errors in its calculation can result in false correlations. The bidimensionality of the data is also confirmed using galaxies belonging to the Virgo or Ursa Major clusters; for each of these two samples, the distance of the galaxies has no statistical influence.
