Might you be able to help me apply the covariate in my model of special populations.
It has been a while since I used NLME, and for some reason I am not able to set it, I keep getting errors during the search step.
The covariate is currently categorical for hepatic impairment set to 0 or 1 for normal function or mild impairment, but I do have continuous covariates in the dataset labeled as ASTULN or BILIULN which are better to use.
I would like to simulate exposures using the continuous covariates (making my own scenarios).
Please see the link to my model below:
