ASYMPTOTIC INFERENCE FOR NONSTATIONARY FRACTIONALLY INTEGRATED AUTOREGRESSIVE MOVING-AVERAGE MODELS [PDF]
Econometric Theory, 2001 This paper considers nonstationary fractional autoregressive integrated moving-average (p,d,q) models with the fractionally differencing parameter d ∈ (− 1/2,1/2) and the autoregression function with roots on or outside the unit circle. Asymptotic inference is based on the conditional sum of squares (CSS) estimation.

A comparison of multiband and multiband multiecho gradient‐echo EPI for task fMRI at 3 T
Human Brain Mapping, Volume 44, Issue 1, Page 82-93, January 2023., 2023 In summary, we found that multiband multiecho (MBME) and MB give a comparable performance in most brain regions with this comparison study. In the regions with dropouts and susceptibility induced inhomogeneity, MBME performed somewhat better at the group level.

Spatial autoregressive fractionally integrated moving average model [PDF]
arXiv, 2023 In this paper, we introduce the concept of fractional integration for spatial autoregressive models. We show that the range of the dependence can be spatially extended or diminished by introducing a further fractional integration parameter to spatial autoregressive moving average models (SARMA).
