RT Journal Article SR Electronic A1 Marcek, Dusan A1 Acova, Michaela T1 Economic Time Series Forecasting: Box-Jenkins Methodology, Signal Processing and Neural Network Approach JF Communications - Scientific Letters of the University of Zilina YR 2003 VO 5 IS 4 SP 55 OP 58 DO 10.26552/com.C.2003.4.55-58 UL https://komunikacie.uniza.sk/artkey/csl-200304-0011.php AB This paper is devoted to the presentation of methods of economic time series analysis and modelling using the Box-Jenkins methodology, the signal processing approach and the feedforward neural network technique. Some results of our research on time series modelling with emphasis on potential improving forecast accuracy are presented here. The assessment of the particular models has been made using the root mean square error.
