For example, if consists of linear models and the error measure is mean squared error, then would be the LMMSE estimate? Thanks a lot!
Yes, best in the current hypothesis set (and should be fixed as you increase N). Note, bias and var are only defined for the MSE error measure, and yes would be the least MSE estimate that is available within (so is independent of N)?
