We consider a long memory time series where the long-memory parameter H appears to change with time. We are interested in detecting and estimating the change-point and studying the asymptotic properties of the estimator and the test statistic. We apply the method to two practical data series to investigate the presence of change in H. Simulations and data examples confirm the validity of the test and estimation. 
A new simple test against spurious long memory using temporal aggregation
A new test against spurious long memory based on the invariance of long memory parameter to aggregation is developed by using the local Whittle estimator, which takes the supremum among combinations of paired aggregated series.
Wilcoxon‐type rank statistics are considered for testing a long‐memory time‐series model with a common distribution against the alternatives involving a change in the distribution at an unknown time

A four-step method based on distances between parameter estimates is proposed, to avoid the optimization problem which criterion based methods may be trapped in when there are a lot of data in the signal series.
Stochastic modelling of financial time series with memory and multifractal scaling
Financial processes may possess long memory and their probability densities may display heavy tails. Many models have been developed to deal with this tail behaviour, which reflects the jumps in the
Segmentation of time series with long-range fractal correlations
A segmentation algorithm which takes as a reference for homogeneity a correlated series modeled by a fractional noise with the same degree of correlations as the series to be segmented, showing the existence of previously unknown huge compositional superstructures in the human genome.
Special Issue of the Journal of Time Series Analysis in Honour of the 35th Anniversary of the Publication of Geweke and Porter‐Hudak (1983): Guest Editors' Introduction
This special issue is a celebration of the 35th anniversary of the publication of John Geweke and Susan Porter-Hudak’s (henceforth GPH) 1983 article, ‘The estimation and application of long memory
Prompt Detection of Changepoint in the Operation of Networked Systems
This paper focuses on a statistical method aiming at detecting changepoint as quickly as possible using Bayes factor along with the binary segmentation procedure modified for fast detection.

A Self‐Normalized Semi‐Parametric Test to Detect Changes in the Long Memory Parameter
We consider the problem of testing for change points in the long memory parameter. The test relies on semi‐parametric estimation of the long memory parameter, which does not require the complete
Change-in-mean problem for long memory time series models with applications
Test and estimation procedures for detecting a change in the mean are proposed in infinite moving average long memory time series models. The asymptotic properties of the test statistics and the


Testing for a change of the long-memory parameter
SUMMARY Long-range dependence is often observed in long time series. Correlations decay approximately like Ik I2"-2, with H E (0 5, 1), as the lag k tends to infinity. The long-term features of the
Change-Point Detection in Long-Memory Processes
We discuss some methods to test for possible changes in the parameters of a long-memory sequence. We obtain the limit distributions of the test statistics under the no-change null hypothesis. The

A Goodness‐Of‐Fit Test for Time Series with Long Range Dependence
We propose a test statistic for goodness of fit in time series with slowly decaying serial correlations. The asymptotic distribution of the test statistic, originally proposed by Milhoj for time
Abstract. The definitions of fractional Gaussian noise and integrated (or fractionally differenced) series are generalized, and it is shown that the two concepts are equivalent. A new estimator of
Semiparametric Analysis of Long-Memory Time Series
We study problems of semiparametric statistical inference connected with long-memory covariance stationary time series, having spectrum which varies regularly at the origin: There is an unknown
Bayesian methods for change‐point detection in long‐range dependent processes
Abstract. We describe a Bayesian method for detecting structural changes in a long‐range dependent process. In particular, we focus on changes in the long‐range dependence parameter, d, and changes
Limit theorems for functionals of moving averages
Let X n = Σ i=1 ∞ a i e n-1, where the e i are i.i.d. with mean 0 and finite second moment and the a i are either summable or regularly varying with index ∈ (-1, -1/2). The sequence {X n } has short
