Hi Yaning,
No apology is necessary. I agree, once we realized that an unbiased
estimate of BSV was estimable...just not using Nick's asymptotic estimate,
we should have realized that we could follow the rest of Nick's logic to
estimate the BOVj.
This discussion has opened my eyes to BOV estimation. In the past whenever
I have estimated BOV I have always used the BLOCK SAME option. I now agree
with Nick that it is good practice to evaluate the full model (estimating
the BOVj) before using the BLOCK SAME option to contrain BOVj=BOV for all j.
You live and learn.
