I don't understand that argument; How is arbitrarily choosing
-xtdpdsys- over -xtabond2- any less manipulative than choosing
particular options of -xtabond2-. The fact that you artificially
reduced the set of choices by ignoring the existence of -xtabond2- did
not make those choices go away. Seems to me you'll just have to learn
what all these models do and make an informed decision about which
model to use.
