From: A discrete Single Delay Model for the Intra-Venous Glucose Tolerance Test
Comparison between different methods of data fitting. Each figure reports Glucose (white circles) and Insulin (black diamonds) observed concentrations versus time, together with the predicted time-curves (dashed line for Glucose and continuous line for Insulin) using four different methods: the discrete Single Delay Model (figure 8.a); the Minimal Model with its traditional two-pass 'decoupling' estimation method (figure 8.b); the Minimal Model when all parameters are fitted simultaneously (figure 8.c); the Minimal Model when global system behavior (interacting glycemias and insulinemias) is reconstructed from separately estimated (two-pass) parameters (figure 8.d).
