Hi Helmut,

❝ Sequence+Subject(Sequence)+Formulation+Period.

❝

❝ To do this, use the following steps:

❝ 1. Start BE Wizard.

❝ 2. Specify reference formulation → Next

❝ 3. Specify dependent variable, e.g. Cmax → Next

❝ 4. Click Delete Random to remove Subject(Sequence) component → Back

❝ 5. Add Subject(Sequence) to the Fixed effects model as shown above

❝ 6. Click Calculate

After doing above correction in WinNonlin, I am observing slight increase in SE as a consequence CI is widening slightly. Also, p-value for sequence is working against 'Residual Error' as error term rater than 'Subject(sequence)' term. How this problem can be fixed and what is the reason for increment of SE ?

Thanks,

Krishna.
