Table 1.

Population data for coefficients u and v from the Eq. 4 in terms of mean, correlation between u and v, and covariance matrix. These figures are for all 10 subjects. When a leave-one-out procedure was used to validate the input function extraction, new figures, derived each time from 9 subjects, were used.

Coefficient	Mean	Correlation	Covariance matrix
			u	v
u	2.40	0.36	0.037	0.017
v	0.66		0.017	0.061
