Nonlinear regression on multiple-dose data.

The examples are given to show how Metzler's nonlinear regression program can be used to estimate parameters in a model with multiple dosing. The model of one example is a set of equations involving sums of exponentials, whereas the other model is a set of differential equations reflecting first order absorption and Michaelis-Menten excretion. In both cases no data were given in one of the dosing intervals.
