Test of independence for high-dimensional random vectors based on freeness in block correlation matrices
In this paper, we are concerned with the independence test for kk high-dimensional sub-vectors of a normal vector, with fixed positive integer kk. A natural high-dimensional extension of the classical sample correlation matrix, namely block correlation matrix, is proposed for this purpose. We then c...
