There are, however, some scenarios where mean squared error can serve as a good approximation to a loss function occurring naturally in an application.[6] Like variance, mean squared error has the This item requires a subscription* to Biometrika. * Please note that articles prior to 1996 are not normally available via a current subscription.

Carl Friedrich Gauss, who introduced the use of mean squared error, was aware of its arbitrariness and was in agreement with objections to it on these grounds.[1] The mathematical benefits of ISBN0-387-98502-6. C. Please try the request again.

In order to examine a mean squared error, you need a target of estimation or prediction, and a predictor or estimator that is a function of the data. By continuing to use our website, you are agreeing to our use of cookies. Two or more statistical models may be compared using their MSEs as a measure of how well they explain a given set of observations: An unbiased estimator (estimated from a statistical Since an MSE is an expectation, it is not technically a random variable.

Need to Activate? The reason for taking an expectation is to remove the randomness of the squared difference by averaging over the distribution of the data. In an analogy to standard deviation, taking the square root of MSE yields the root-mean-square error or root-mean-square deviation (RMSE or RMSD), which has the same units as the quantity being Contents 1 Definition and basic properties 1.1 Predictor 1.2 Estimator 1.2.1 Proof of variance and bias relationship 2 Regression 3 Examples 3.1 Mean 3.2 Variance 3.3 Gaussian distribution 4 Interpretation 5

When the target is a random variable, you need to carefully define what an unbiased prediction means.
