The difference between total error, prediction error and fitted error via residual
Fitted error = $E(Y|X)-\hat{Y}$. Further, define residual = $Y-\hat{Y}$. Now, we have $Total \ error = Residual
\ error + Fitted \ error$. … Therefore, the total error can be expressed as $Total \ error = Prediction \ error + 2 \times Fitted
\ error$.
Is the above derivation regarding errors, is right or wrong? …
