Fractional Integration and Cointegration [PDF]

open access: yes, 2023
Fractionally integrated and fractionally cointegrated time series are classes of models that generalize standard notions of integrated and cointegrated time series. The fractional models are characterized by a small number of memory parameters that control the degree of fractional integration and/or cointegration.

Use of fresh water over the long run measuring persistence

open access: yesWater Policy, 2022
In this article, we carry out a study of the degree of persistence of a time series of data on freshwater use in the long term, using fractional integration or I(d) techniques. Using annual data from 1901 to 2014, we observe that the order of integration

Fractional integral inequalities involving Marichev–Saigo–Maeda fractional integral operator [PDF]

open access: yesJournal of Inequalities and Applications, 2020
AbstractThe aim of this present investigation is establishing Minkowski fractional integral inequalities and certain other fractional integral inequalities by employing the Marichev–Saigo–Maeda (MSM) fractional integral operator. The inequalities presented in this paper are more general than the existing classical inequalities cited.

Fractionally Integrated COGARCH Processes* [PDF]

open access: yesJournal of Financial Econometrics, 2018
We construct fractionally integrated continuous-time GARCH models, which capture the observed long range dependence of squared volatility in high-frequency data. Since the usual Molchan-Golosov and Mandelbrot-van-Ness fractional kernels lead to problems in the definition of the model, we resort to moderately long memory processes by choosing a ...
