Dear All,

One doubt regarding the above mentioned FDA recommended SAS code.

How can I include a SUB(SEQ) term in the above SAS code?

Why the covariance structure FA0(2) is used in this code? Why not the other covariance structures? Is there any method to choose the covariance structure?

Why DDFM=satterth? Why not DDFM=kenwardroger?

Regards

Matz
