Chapter 20. Advances in Forecast Evaluation This chapter surveys recent developments in the evaluation of point forecasts. Taking West’s (2006) survey as a starting point we briefly cover the state of the literature as of the time of West’s writing. We then focus on recent developments including advancements in the evaluation of forecasts at the population level (based on true unknown model coefficients) the evaluation of forecasts in the infinite sample (based on estimated model coefficients) and the evaluation of conditional versus unconditional forecasts. We present original results in a few subject areas: the optimization of power in determining the split of a sample into in sample and out of sample portions; whether the accuracy of inference in evaluation of multi step forecasts can be improved with judicious choice of heteroskedasticity and autocorrelation estimator (it can); and the extension of West’s (1996) theory results for population level unconditional forecast evaluation to the case of conditional forecast evaluation.
