Abstract

This note outlines the steps for proving that the moments of a randomly-selected subset of a general ETF (complex, with aspect ratio 0<γ<10<\gamma<1) converge to the corresponding MANOVA moments. We bring here an extension for the proof of the 'Kesten-Mckay' moments (real ETF, γ=1/2\gamma=1/2) \cite{magsino2020kesten}. In particular, we establish a recursive computation of the rrth moment, for r=1,2,r = 1,2,\ldots, and verify, using a symbolic program, that the recursion output coincides with the MANOVA moments.
