Statistic definition Statistics are facts which are obtained from analysing information expressed in numbers , Meaning, pronunciation, translations and examplesS is known both as the standard error of the regression and as the standard error of the estimate S represents the average distance that the observed values fall from the regression line Conveniently, it tells you how wrong the regression model is on average using the units of the response variableDefinition Suppose that we have a statistical model of some data Let k be the number of estimated parameters in the model Let ^ be the maximum value of the likelihood function for the model Then the AIC value of the model is the following = (^) Given a set of candidate models for the data, the preferred model is the one with the minimum AIC value
