WebFeb 4, 2024 · The evaluation of Gaussian moments is a classical problem dating back to Isserlis , in the case of real vectors. In the case of complex Gaussian vectors, the product moment is related to Wick’s theorem (Wick, 1950), to Boson point processes McCullagh and Møller , and to Feynman diagrams. The complex case is a little simpler than the real ... In probability theory, Isserlis' theorem or Wick's probability theorem is a formula that allows one to compute higher-order moments of the multivariate normal distribution in terms of its covariance matrix. It is named after Leon Isserlis. This theorem is also particularly important in particle physics, where it … See more • Wick's theorem • Cumulants • Normal distribution See more • Koopmans, Lambert G. (1974).

If (F WebThe second centered moment is the variance, hx2i= R 1 1 x2P(x)dx; the third centered moment is called the skew, and the fourth the kurtosis. To compute these moments, we use the fact that y= x ˙ is a zero-mean Gaussian variable with unit variance. Thus, if we can compute the moments of y, e.g., hyni, then we can compute the moments of z, e.g. by
