Central limit theorem for high temperature spin models via martingale embedding
Xiao Fang, Yang Xie, Yi-Kun Zhao
We use martingale embeddings to prove a central limit theorem (CLT) for one-dimensional projections of high-dimensional random vectors in satisfying a Poincaré inequa…

Normal approximation for exponential random graphs
Xiao Fang, Song-Hao Liu, Qi-Man Shao +1
The question of whether the central limit theorem (CLT) holds for the total number of edges in exponential random graph models (ERGMs) in the subcritical region of parameters has r…
