... respect to b when b = 0 .. ( 14 ) The minimax approach thus leads to the criterion of unbiasedness . In order that the linear estimator ( 5 ) be unbiased , it is necessary and sufficient that EB - AEY + b = AXB + b = B identically in B ...

... respect to B when B = b . Proof : We have Y - XB - Y - Xb + X ( b − B ) = EY + X ( b - B ) where E - I - X ( X'X ) - ' X ' . Noting that EX = 0 and E2 = E = E , - Ɛ'Ɛ = ( Y — XB ) ' ( Y - XB ) = Y'EY + ( b − B ) ' X'X ( b − B ) . This ...
