Holonomic gradient method for the distribution function of the largest root of a Wishart matrix
Hiroki Hashiguchi, Yasuhide Numata, Nobuki Takayama +1
We apply the holonomic gradient method introduced by Nakayama et al.(2011) to the evaluation of the exact distribution function of the largest root of a Wishart matrix, which invol…
