Dear Niurys, It would be down to distributional assumptions in that case. For example if you have a very strong predictor (covariate

Hi Niurys, Depending on the size of your peptide and the timing of the first observations, it might also be likely that the rate limiting step for the terminal elimination phase is the (re)distribution from the peripheral to the central compartment, rather than the absorption. This is nicely demon

This is an interesting discussion. At the same time I can't get my head around the assumption of any covariate on a flip-flop phenomenon. In other words, even if there is no information on covariates this phenomenon could still exist. It's my understanding that this flip-flop phenomenon is fundame

Dear Niurys, It would be down to distributional assumptions in that case. For example if you have a very strong predictor (covariate) of either elimination or absorption rate (but not both) - data could be informative to discriminate between flip-flop or not. Had your therapeutic been IgG monoc

Dear nmusers, I'm working on the population PK of a therapeutic peptide candidate for rheumatoid arthritis. Three dose levels of the peptide were administered as a single subcutaneous injection. We have some limitations, for instance, the dataset is very sparse and is lacking in the information of
