abstract

Inspired by \citet{Berkes14} and \citet{Wu07}, we prove an almost sure invariance principle for stationary $\beta-$mixing stochastic processes defined on Hilbert space. Our result can be applied to Markov chain satisfying Meyn-Tweedie type Lyapunov condition and thus generalises the contraction condition in \citet[Example 2.2]{Berkes14}. We prove our main theorem by the big and small blocks technique and an embedding result in \citet{gotze2011estimates}. Our result is further applied to the ergodic Markov chain and functional autoregressive processes.

  1. Prokhorov Metric Convergence of the Partial Sum Process for Reconstructed Functional Data

    math.ST 2025-06 conditional novelty 7.0 of 10

    For dependent, approximately stationary random functions in C0, the partial sum process is within O(N^{-τ}) of a functional Brownian motion in Prokhorov and Wasserstein distance.

  2. Choosing the Right Norm for Change Point Detection in Functional Data

    math.ST 2025-01 conditional novelty 7.0 of 10

    An L1-norm based change point test for functional time series is introduced, with bootstrap validity, theoretical power comparisons, and a power enhancement against sparse alternatives.
