We compare the forecasts with Generalized Autoregressive conditional Heteroskedasticity (GARCH) and Autoregressive Integrated Moving Average (ARIMA) models. The results indicate that GRNN outperform significant the conventional econometric models and can be an efficient alternative tool for forecasting. The MATLAB algorithm we propose is provided in appendix for further applications, suggestions, modifications and improvements. date: 2011 type: Article type: PeerReviewed format: application/pdf language: en identifier: http://eprints.imtlucca.it/1638/1/IJARCS_Giovanis_2011.pdf identifier: Giovanis, Eleftherios Application of a Modified Generalized Regression Neural Networks Algorithm in Economics and Finance.
