Time-varing covariate
Hi, Dear NMusers:
I want to add a time-varing covariate in my model. For example, blood
pressure or blood flow as covariates. But I am not sure how to do it. I see
some earlier threads to discuss it but they all use complicated methods.
I am wondering if there are any new way to do it in NM 7.2? I see in the
user guide that EVID=4 can indicate physiological change. Is this what I
should use?
Thank you very much for any suggestions.
Best regards,
Siwei
