We investigate the distribution and correlation of properties of these models, including the number of generations and the hidden sector gauge group. Compared to the recent analysis hep-th/0510170 of models with a standard model-like gauge group, we find very similar results.4 pages, 7 figures, revtex; v2: version to be published in prd, minor extension of flipped SU(5) discussion, plots updatedHigh Energy Physics - TheoryHigh Energy Physics - Phenomenologytext
