Stein`s method and central limit theorems for Haar distributed
... The observation that random matrices, picked according to Haar measure from orthogonal groups of growing dimension, give rise to central limit theorems, dates back at least to Émile Borel, whose 1905 result on random elements of spheres can be √ read as saying that if the upper left entry of a Haar ...
