Variance is a measure of dispersion. It is equal to the average squared distance of therealizations of a random variablefrom its expected value. Definition A formal definition of variance follows. DefinitionLet be arandom variable. Denote theexpected valueoperator by . Thevarianceof is provided the...
Expected Squared Error In subject area: Computer Science Expected Squared Error refers to the average of the squared differences between an estimated value and the true value, comprising of a variance term and a bias term.
