Dear Ken and All
I wonder, as Mats did, how useful estimating BOV separately for
different occasions really is. I could see certain cases where one
might have reason to believe that BOV would be substantially different
on different occasions, but for the most part it doesn't seem that this
would necessarily be the case. And in terms of model building strategy,
at what point would one conclude that the BLOCK SAME option is
reasonable? What is the impact on the THETA values (and the BOV) of
wrongly assuming the BLOCK SAME? I would guess it is minimal but
perhaps not.
