st: clarification on interpreting Stock&Yogo- maximal IV "size"

["Nirina F" <fstata@gmail.com>]

Dear all,

Yes, I read
  Stock, J.H. and Yogo, M.  2005. " Testing for Weak Instruments in
Linear IV Regression"

but I still don't understand how do I interpret the critical values of
 the Stock&Yogo- maximal IV size when using ivreg2.

I think I compare the critical values from  x%maximal IV relative bias
with the Cragg-Donald stat to test for weak instruments but the
critical values for the size with what and what it means?

Thanks a lot in advance
