### 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`
