Forecasting in Business Research Using the ARIMA Box-Jenkins Methodology

Abstract:

Over the years, several techniques have been developed to deal with diverse forecasting situations, falling broadly into quantitative and qualitative (or technological) techniques. Qualitative methods are basically subjective and judgmental inputs of experts in the field. These are considered to be most appropriate when historical data and/or scientific expertise are not available. In some cases, they may even be preferred, as in very long-range forecasting.
