Figure 4From: Statistical learning methods as a preprocessing step for survival analysis: evaluation of concept using lung cancer data Survival probability curves for z. The upper and lower-z groups were formed by dichotomizing the total collection of patients at their median z value. The upper-z group (upper brown curve) exhibits better survival characteristics than the lower-z group (bottom blue curve). These findings incorporate tumor-grade with age via the probabilistic neural network combination.Back to article page
