Bootstrap testing for discontinuities under long-range dependence

Beran, Jan; Shumeyko, Yevgen - In: Journal of Multivariate Analysis 105 (2012) 1, pp. 322-347

We consider testing for discontinuities in a trend function when the residual process exhibits long memory. Using a wavelet decomposition of the estimated trend function into a low-resolution and a high-resolution component, a test statistic is proposed based on blockwise resampling of estimated...
