K-th Moving, Weighted and Exponential Moving Average for Time Series Forecasting Models

The objective of the present study is to investigate the effectiveness of developing a fore- casting model of a given nonstationary economic realization using a k− th moving average, a k− th weighted moving average and a k− th exponential weighted moving average process. We create a new nonstationary time series from the original realization using the three different weighted meth- ods. Using real economic data we formulate the best ARIMA model and compare short term forecasting results of the three proposed models with that of the classical ARIMA model. 2000 Mathematics Subject Classifications: 62M10, 91B84
