Abstract
We use multivariate statistical analysis to study the relation between the globular cluster content of early-type galaxies and a number of their observed properties. The number of globular clusters scales non-linearly with galaxy luminosity and virial mass. Both the total number of clusters and their specific frequency correlate with metallicity, internal velocity anisotropy, isophotal shape parameters and, possibly, X-ray luminosity of the host galaxy. We observe that the properties of the globular cluster systems, to a large extent, are correlated with the so-called Fundamental Plane of early-type galaxies, although a residual amount of variability in the number and specific frequency of globulars remains
