FIN.18:11 - SoTA-Echoing

MA’s forecasting contributions make purpose and consequential differences central; C.11.DUA relates demanded inquiry to its receiving value. FIN.18 applies these ideas to current finance methods and relevant professional sources. It rejects novelty or fit alone as a selection rule; a new failure or materially better attainable method reopens the choice.

The current online third edition of Hyndman and Athanasopoulos, Forecasting: Principles and Practice, §5.8 distinguishes genuine forecast errors from fitted residuals and explains several error measures. §5.10 develops evaluation at successive forecast origins and the relevant horizon. FIN.18 adopts those information boundaries; its constructed funding comparison adds the actual response and burden. RMSE can support a forecast comparison; the financial choice also depends on the available response and its cost. The direct FIN Methods supply the distinct valuation, exposure and execution comparisons, while C.11.DUA supplies the decision about additional inquiry.
