partial replicate? [Software]
Dear dixit, ambati?,
I guess your design is eventually a partially replicate design (only Reference replicated, RTR/TRR/RRT)?
In that design one would expect sigma2T not identifiable because Test was not administered replicated.
Then using the FDA code results in over-specifying the model. See this thread.
One hint for this is the result for residual Test in your output above.
But don't ask me for an other implementation in SAS for that design. I was up to now not able to figure it out and had also not been successful in finding a reference. Sorry
