Hi,

 

I am building a pop PK model for L-Dopa. After I mapped my covariates, I ran the model, but I I am receiving a strange error saying that covariate for subject are not set. It starts with first covariate for first subject. After removing that covariate, it gives error for second covariate in a row.  So I would appreciate it if you help me with this problem.

Hi Amir,

 

there is no screenshot of your error message. We would need your Phoenix project file to diagnose the root cause. Could you share? If not, please send a message to support@certara.com where we could handle it as well.

this error mostly occur when your subject has no value at all for a covariate i.e missing

 

it is your responsibility to impute put the value you want in the data 

 

if there is a value at the start of the subject it will be carried forward automatically but we still need a value at the start

check your data for the first subject and send a screenshot  or the whole project as Bernd asked
