I am running some data using a 1 compartment or a 2 compartment models un PopPK module with a FOCE ELS algorithm. However, when I get the theta values they lack the CV%, the CI and the Stderr values while they are returned with the 1 compartment model. If I choose to run the QRPEM algorithm, then all those parameters and calculated for both models.
- Is there a reason why I cannot get the CV, CI, etc with the FOCE ELS for 2 compartment model?
- In order to choose between both models, would AIC be affected whether FOCE ELS or QRPEM algorithms are used (for both)?
