High Frequency Data: Making Forecasts and Looking for an Optimal Forecasting Horizon
Result description
We illustrate the AutoRegessiveiGeneralised collditionaliy Heteros§cedastic (ARCH-GARCH) methodology on the developing a forecast mode! for exchange rates time series of the Czech crown (CZK) againsr the Slovak crown (SKK) and make comparisons the forecast accuracy with the class of Radial Basic Functiov Neural neural network RBF NN models. To illustrate the forecasting performance of these approaches the inIJu t/r.utput function estimation based on REF networks is presented. III a comparative study isshown that the RBF NN approach is able to model and predkt high frequency data with reasol1abie accuracy and more efficient than statistical methods. In order to find the optima! forecasting horizon, we use the analysis of fo recast errors and choose tntvalues that give the smallest error variance. It is found that the error variance estimation process based on soft methods is simplified and less critical to the question whether the data is true crisp or white noise.
