Estimation of the bispectrum for locally stationary processes
Paparoditis Efstathios, E.; Preuß, P. (2014)We consider the problem of estimating the bispectrum of a locally stationary process. A nonparametric, lag-window type estimator is considered and its asymptotic properties are investigated. As a possible application, a ...

On Local Power Properties of Frequency Domain-based Tests for Stationarity
Paparoditis Efstathios, E.; Preuß, P. (2016)A framework for the asymptotic analysis of local power properties of tests of stationarity in time series analysis is developed. Appropriate sequences of locally stationary processes are defined that converge at a controlled ...
