A general Isserlis theorem for mixed-Gaussian random variables
WebJul 11, 2003 · For this purpose we need to generalize the q-Wick theorem to products of q-Wick products. Given q -Gaussian random variables {ξ p , k } with 1 ≤ p ≤ t and 1 ≤ k ≤ n p , we may regard the index set S = {( p, k )} as partitioned by the first integer, and we refer to each partition as a “block.” http://www.laine.itp.unibe.ch/exercises/section1.pdf iiht corporate office
