Dear Peter,
I have no answer unless maybe you are using on old version (late 2000) which
may have had a bug. The current version is dated March 2001.
While you will get different values in the .sln file,
the predicted values should be identical from the models
yield ~ mu c(TrialID)
yield ~ mu TrialID
yield ~ TrialID
