Table 2.

Results of discriminant function analysis for tumor growth and formation using the expression of four marker genes as predictor variables. Overall statistics for tests: Growth type (five groups) Wilks’ Lambda:.04104 approx. F (16,248) = 28.593 P < 0.0001, N = 89; Tumor formation (five groups) Wilks’ Lambda:.03375 approx. F (16,251) = 31.897 P < 0.0001, N = 90. Significant predictors are in italic font.
