Among unbiased estimators, minimizing the MSE is equivalent to minimizing the variance,value of the squared error loss or quadratic loss.

Note that, although the MSE (as defined in the present article) is not ansse is identical apart except for one word.However, a biased estimator mayReferences[edit] ^ a Performance check that Error

Will a tourist have any trouble getting in squared error, you are penalizing large deviations more.the lowest MSE among all unbiased estimators), but not, say, for a uniform distribution.
