New Gaussian Approximation Bounds for Markov Chains Developed

Researchers have developed new Gaussian approximation bounds for sums of multivariate martingale differences derived from uniformly ergodic Markov chains. These bounds, expressed in higher-order Wasserstein distance, achieve an optimal rate of O(n^{-1/2}) for fixed dimensions and orders. The methodology introduces novel techniques to manage the complexities of temporal dependence and higher-order Wasserstein distances, potentially offering broader applications in statistical analysis under such conditions.

    Gaussian Approximation for Multivariate Martingale Sums from Uniformly Ergodic Markov Chains

    arXiv:2609.09480v1 Announce Type: cross Abstract: We develop Gaussian approximation bounds in higher-order Wasserstein distance $W_p$, $p\geq2$, for sums of multivariate martingale differences generated by a uniformly ergodic Markov chain. Under an $L^{(2+\eta)p}$-moment conditio…
