Model Description
*****************


:Name: weight_covariate

:Title: Body Weight Covariate

:Author: PoPy for PK/PD

:Abstract: 

| One compartment model with absorption compartment and CL/V parametrisation.
| There are no random effects here. Each individual just has a different weight.
| The weight is a covariate for the m[CL] clearance parameter for each individual.
| Only the f[WT_EFFECT] and f[V] fixed effect parameters are estimated, other f[X] are fixed.

:Keywords: one compartment model; dep_one_cmp_cl; weight; covariate effect
