I think that Greg had this right several years ago: it would probably
be very useful to have the input of someone with a strong background
in statistics. It doesn't seem that important that they already know a
lot about databases, provided they can understand what our constraints
are, and what is important to us. It might just be a matter of having
them point us in the right direction.
