F. Decision surfaces for logistic regression classifier. Cells with self-renewing (red) or differentiated (green) pro-fates are plotted above the predicted class surfaces. (left) Slice of decision surface for pulse frequency vs. OCT4 levels at a cell cycle duration of 14 h. (right) Slice of decision surface for cell cycle duration vs. OCT4 level at a pulse frequency of 0.25 h-1. * P < 0.05, ** P < 0.0005; ns, not significant.
