From above message the output 4 period replicate FDA template is repeated as follows:

Dependent Parameter Estimate
ln Cmax lambda(1,1)_11 is 0.82840679
ln Cmax lambda(1,2)_11 is 0.85299475
ln Cmax lambda(2,2)_11 is 5.63E-07
ln Cmax Var(Period*Formulation*Subject)_21 is 0.11739425
ln Cmax Var(Period*Formulation*Subject)_22 is 0.20211805

From Ana’s message the value for subj. formulation interaction(sig_D^2) is as follows:

(0.82840679)+(5.63E-07)-2*(0.85299475)= -0.87758

Here are my results from the same data set in Phoenix: my input structure is different
Data lambda(1,1)_11 0.85299471
Data lambda(1,2)_11 0.82840678
Data lambda(2,2)_11 8.34E-07
Data Var(Period*Formulation*Subject)_21 0.20211811
Data Var(Period*Formulation*Subject)_22 0.11739421

I used BABA for the input for the first subject. If you look at the Parameter Key and Group Levels on the Parameter Key Output Workbook in Phoenix I have first output parameter as reference not test. That is why there is transposition in the parameter values.
