  However, you can imagine situations where a trade-off exists between the two: one estimator may be have a small bias but a much smaller variance than another, unbiased estimator. The concept of mean square error estimator combines the two concepts. Let be an estimator of . Then the mean square error (MSE) is defined as follows: MSE( ) = E(  )2. Prove that MSE( ) = bias2 + var( ). (Hint: subtract and add in E( ) in E(  )2.)
