Also for Pop PK, I doubt how precise you can estimate your parameters, because generally you need 1 sample /subject /parameter. So if you only have one sample per subject, then it will be hard to estimate every parameter, unless you fix some based on literature report and estimate part of parameter. Yan Feng
