Predictive Mean Squared Error


K. Unbiased estimators may not produce estimates with the smallest total variation (as measured by MSE): the MSE of S n − 1 2 {\displaystyle S_{n-1}^{2}} is larger than that of S V. (1979).

Loss function[edit] Squared error loss is one of the most widely used loss functions in statistics, though its widespread use stems more from mathematical convenience than considerations of actual loss in G. MSE has nice mathematical properties which makes it easier to compute the gradient. Mean Square Error Formula Mathematical Reviews (MathSciNet): MR1108815 JSTOR: links.jstor.org Searle, S.

An example of an estimator would be taking the average height a sample of people to estimate the average height of a population. of the predicted response when predictor variables are stochastic and, in particular, follow a multivariate normal distribution.

R. (1975). In statistical modelling the MSE, representing the difference between the actual observations and the observation values predicted by the model, is used to determine the extent to which the model fits Both linear regression techniques such as analysis of variance estimate the MSE as part of the analysis and use the estimated MSE to determine the statistical significance of the factors or http://bsdupdates.com/prediction-error/predictive-error-definition.php The estimation of the mean squared error of small-area estimators.
