The parameters Inline graphic 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 R ² is the square of the multiple correlation coefficient.
