In Simbiology, should the categorical variables be assigned as group variable or covariate in the dataset?

1 view (last 30 days)
I am using Simbiology for population pharmacokinetic model development. I use non-linear mixed effect modelling approach. I have a doubt in the intial assignment of data type in the dataset.
Suppose I have age and gender in the dataset. Clearly, I will assign age as covariate. Now gender is also a covariate. But there is a option in the dataset type which is group variable.
Now I am confused on whether I should assign gender as covariate or group variable.?
I am attaching a screenshot for the reference.

Oh. That's a clear answer. I have a logical query. Among the covariate, one is a categorical variable (gender) and another is a continuous variable (age). How do I incorporate this information in the dataset / modelling?

Group variable defines an index for a subject/experiment. In your dataset, ID is a group variable. Gender and age can be both covariates.
