Performing the VPC of categorical covariate

Phoenix Certara Forums NLME-NONMEM model comparisons

Dear all

I am currently working on the development of PopPK model of compound X to determine gender difference.

So I incorporated gender as a covariate in the model and gender affected the CL.

Therefore, I want to perform VPC by gender but how can I get the VPC result separated by gender?

Thanks to all in advance.

Hi you need to define the covariate as categorical using the user interface or in code :

fcovariate(gender())

then this covariate will be come available in the stratification options
