The idea of fractional differencing is introduced in terms of the infinite filter that corresponds to the expansion of (1 − B) d.When the filter is applied to white noise, a class of time series is generated with distinctive properties, particularly in the very low frequencies and provides potentially useful long-memory forecasting properties. is there school on monday next week
