MODELLING FOR THE WAVELET COEFFICIENTS OF ARFIMA PROCESSES [PDF]
AbstractWe consider a model for the discrete nonboundary wavelet coefficients of autoregressive fractionally integrated moving average (ARFIMA) processes in each scale. Because the utility of the wavelet transform for the long‐range dependent processes, which many authors have explained in semi‐parametrical literature, is approximating the transformed ...

Maximum likelihood estimation of stationary multivariate ARFIMA processes [PDF]
This article considers the maximum likelihood estimation (MLE) of a class of stationary and invertible vector autoregressive fractionally integrated moving-average (VARFIMA) processes considered in Equation (26) of Luceno [A fast likelihood approximation for vector general linear processes with long series: Application to fractional differencing ...

SMALL-SAMPLE LIKELIHOOD-BASED INFERENCE IN THE ARFIMA MODEL [PDF]
The autoregressive fractionally integrated moving average (ARFIMA) model has become a popular approach for analyzing time series that exhibit long-range dependence. For the Gaussian case, there have been substantial advances in the area of likelihood-based inference, including development of the asymptotic properties of the maximum likelihood ...

A FRACTIONAL ARIMA (ARFIMA) MODEL in the ANALYSIS of HISTORICAL CRUDE OIL PRICES
We investigate historical data for crude oil prices using autoregressive fractionally integrated moving average (ARFIMA) models to determine whether shocks in the series have transitory or permanent effects.
