# Predicted Mean Square Error

## Contents

References ^ a b Lehmann, E. If you plot the residuals against the x variable, you expect to see no pattern. MSE is also used in several stepwise regression techniques as part of the determination as to how many predictors from a candidate set to include in a model for a given chemoreception Process by which organisms respond to chemical stimuli in their environments that depends primarily on the senses of taste and smell. http://bsdupdates.com/prediction-error/predicted-error.php

The difference occurs because of randomness or because the estimator doesn't account for information that could produce a more accurate estimate.[1] The MSE is a measure of the quality of an JSTOR, the JSTOR logo, JPASS, and ITHAKA are registered trademarks of ITHAKA. game theory Branch of applied mathematics that provides tools for analyzing situations in which parties, called players, make decisions that are interdependent.

## Mean Squared Prediction Error In R

That is, the n units are selected one at a time, and previously selected units are still eligible for selection for all n draws. The solution is the conditional expectation... The minimum excess kurtosis is γ 2 = − 2 {\displaystyle \gamma _{2}=-2} ,[a] which is achieved by a Bernoulli distribution with p=1/2 (a coin flip), and the MSE is minimized
