Figure 5. Classification and alignment accuracies resulting from using different B-splines for interpolation.

All replicates of the observation tested are purged from the database. The top line shows classification accuracy, in which the correct treatment is chosen. The bottom lines show alignment accuracy, where the predicted time is within 24 and 12 hours respectively of the actual time. Highlighted points are significantly different from the linear case (p≤0.05 via McNemar's χ ² test).
