The Estimated Model Parameters and the Squares of the Multiple Correlation Coefficients (R2) for the Fits of the Experimental Cortisol Time Series.

The parameters and are, respectively, the estimated infusion rate of cortisol into the circulation from the adrenal glands and the estimated clearance rate of cortisol by the liver. N is the estimated number of hormone pulses and R2 is the square of the multiple correlation coefficient.
