After reading your post again, Maarten, can I ask how I can use suest to circumvent the correlation between different models' error terms?
Thanks,
Zitian

-suest- does not explicitly model any correlation between the models'
error terms, it circumvents that problem by using a variance
covariance matrix of the sandwich/robust type. So I am not surprised
by what you find.
