comment Quantifiers in function definition — is this legitimate?
The context is statistics. Θ is the parameter space, and the functional is an expectation. In notion 2, the idea is to restrict consideration of the functional to just the physically real value of the parameter. I confess to being surprised that this is legitimate -- I thought such quantifiers could only be applied to a formula with a free variable, yielding a proposition with a definite truth value (or another formula with a free variable, of course).
