A pharmacokinetics example : theophylline<br />

y ij =<br />

D i ka i ke i<br />

Cl i (ka i − ke i )<br />

(e −ke i t ij<br />

− e −ka i t ij<br />

)<br />

+ ε ij<br />

For subject i,<br />

the vector of regression (or design) variables is x ij = (D i , t ij ),<br />

the vector of individual parameters is<br />

φ i = (log(ke i ), log(ka i ), log(Cl i )),<br />

the only available covariate is the weight w i .<br />
