Hi All
I am modeling a large crossover study with many dosing occasions per subject. I have IOV on several parameters. There are covariates which change between occassions, e.g. DOSE or ROUTE.
I would like to visualize DOSE vs the IOV, to perhaps screen for covariate effects. The issue is, EtaCovariate, and the corresponding standard phoenix plot outputs, only have the covariate for the first occasion, so observing COV-ETA for all occasions is not possible.
I could do a work around IF there was a pattern between occasion and the covariate - but it is a random crossover study, so that isn't feasible.
I think your current implementation is the best in general, but doesn't work for my specific use case. Any idea for a work around?
Thanks,
Justin
