Multivariate statistical analysis is used to correlate the estimated total numbers of globular clusters in elliptical galaxies (Ngc), and the numbers per unit luminosity (SN), with a variety of observed properties of the host galaxies. Both Ngc and SN are correlated with the so-called fundamental plane of elliptical galaxies, suggesting that the processes which determine global properties of ellipticals also largely determine their globular cluster content, although a considerable residual scatter remains. The redder (presumably more metal-rich) galaxies were found to have more globular clusters, implying that a dissipative formation mechanism was involved. Galaxies which have more anisotropic velocity distributions were also found to have more clusters, suggesting that mergers may have been important in the production of globular systems.
