Some new evidence using fractional integration about trends, breaks and persistence in polar amplification [PDF]
Scientific ReportsThis paper uses fractional integration methods to obtain new evidence on polar amplification. The adopted modelling framework is very general since it allows the differencing parameter to take any real value, including fractional ones, and provides ...

Humbert generalized fractional differenced ARMA processes
Communications in Nonlinear Science and Numerical Simulation, 2023 In this article, we use the generating functions of the Humbert polynomials to define two types of Humbert generalized fractional differenced ARMA processes. We present stationarity and invertibility conditions for the introduced models. The singularities for the spectral densities of the introduced models are obtained.

Nonfractional Long-Range Dependence: Long Memory, Antipersistence, and Aggregation
Econometrics, 2021 This paper used cross-sectional aggregation as the inspiration for a model with long-range dependence that arises in actual data. One of the advantages of our model is that it is less brittle than fractionally integrated processes.
