Eric and all -
He explains this notation on pages 21-22. Theta-bar means a given
"hypothetical model" of theta, which is taken to represent the
unknowable "true" value of theta which we can only guess at.

Starting with the \theta on the first page of chapter

several formulae that follow with a \bar notation. What does this
\bar notation indicate?
We see it again on equation 4.4, this time on \beta.
Thanks!
