Monitoring long‐memory air quality data using ARFIMA model
Environmetrics, 2007AbstractStatistical control chart is commonly used in the industry to help ensure stability of manufacturing process and it can also be used to monitor the environmental data, such as industrial waste or effluent of manufacturing process. However, control chart needs to be modified if the set of environmental data exhibits the property of long memory ...

Empirical study of ARFIMA model based on fractional differencing
Physica A: Statistical Mechanics and its Applications, 2007Abstract In this paper, we studied the long-term memory of Hong Kong Hang Sheng index using MRS analysis, established ARFIMA model for it, and detailed the procedure of fractional differencing. Furthermore, we compared the ARFIMA model built by this means with the one that took first-order differencing as an alternative.

A Generalized ARFIMA Model with Smooth Transition Fractional Integration Parameter
Journal of Time Series Econometrics, 2017AbstractThis paper proposes a model of time-varying fractional integration where the long-memory parameter,d$d$, in an ARFIMA model is allowed to depend ont$t$and evolve according to a Smooth Transition Regressive (STR) model advanced by Teräsvirta (1994, 1998) . To estimate the time-varying fractional integration parameter, we suggest a new multi-step

Estimation and testing of ARFIMA models in the real exchange rate
International Journal of Finance & Economics, 2002AbstractThe Purchasing Power Parity (PPP) hypothesis is one of the most important theoretical relationships in international economics. However, its empirical support remains controversial. We propose an alternative way of modelling the real exchange rate in five industrialized countries in relation to the US dollar, by means of fractionally integrated

Forecasting comparisons using a hybrid ARFIMA and LRNN models
Communications in Statistics - Simulation and Computation, 2017In this article, an autoregressive fractionally integrated moving average model (ARFIMA) and a layer recurrent neural network (LRNN) were combined to form a hybrid forecasting model.

ARFIMA model decomposition for hydrological time series
2004In questo lavoro viene proposta una procedura statistica per la decomposizione di processi ARFIMA(p,d,q) in componenti elementari. Il problema viene ricondotto a quello della decomposizione di un processo ARMA(p+1,q+1) sfruttando il modello ARMA(1,1) come ’proxy’ della componente di lunga memoria.
