Lack of CV% in Theta page

Phoenix Certara Forums Modelling and Simulation
1

Hi all,

I have rat PK data for 4 formulations. One of the formulation (group 2) is the fast-releasing patch. I used the mean concentration from group 2 animals for PK modeling. I ran the model with good fitting and diagnostic plot and the return code of 1. However, in the Theta page, there is a lack of CV% and related statistics info.

Would it be a problem? Could anyone please help to find out the reason for this?

Looking forward for your suggestions.

Peggy
