NettetMore on Gaussian r.vs: From Lecture 7, X. and . Y. are said to be jointly Gaussian as if their joint p.d.f has the form in (7-23). In that case, by direct substitution and simplification, we obtain the joint characteristic function of two jointly Gaussian r.vs to be . 1 ( , ) ( ) 0, 0 2 2 = = ∂ ∂ ∂Φ = u v XY. u v u v j E XY Nettet5. mai 2024 · Homework Statement. Find the characteristic function, for the joint gaussian distribution: Where C is a real symmetric matrix and C-1 is its inverse. (Note that the -1 is an exponent, not subtraction of the identity matrix. Anytime I write X-1 I'm talking about the inverse of the matrix X). island heat pumps nl
