The minimal models of glucose-insulin kinetics were used to analyze sets of data obtained from human subjects and dogs during frequently sampled intravenous glucose tolerance tests (FSIGTs). Analysis of some data sets from both species resulted in poor identification of parameters. To improve the parameter resolution, the information base on which the parameters are estimated was enlarged. This was accomplished by incorporating into the analysis 1) glucose data obtained between 0 and 8 min of the FSIGT and some of the insulin data obtained prior to the insulin peak and 2) a second set of FSIGT data for each individual obtained during a physiological perturbation. As a result, data analysis w..View full abstract
