Description

Name:pa_gen_pa_fit_badvar
Title:Mixed error model fitted to mixed error data, but with incorrect variance definition
Author:Wright Dose Ltd
Abstract:
One compartment model with a depot leading to a central compartment
This model contains both proportional and additive error, but erroneously sums the standard deviations.
Keywords:one compartment model; dep_one_cmp_cl; proportional and additive error
Input Script:pa_gen_pa_fit_badvar.pyml
Input Data:synthetic_data.csv
