 Subject: Assume X; Y and Z are jointly Gaussian mean-zero random variables with the (joint) variance given by K := Var(X; Y;Z) =[2 1 0;1 2 1;0 1 2 ] From: pramod kumar Date: 20 May, 2012 18:34:07 Message: 1 of 2 Assume X; Y and Z are jointly Gaussian mean-zero random variables with the (joint) variance given by K := Var(X; Y;Z) =[2 1 0;1 2 1;0 1 2 ] (a) Determine the distribution of U = X + Y + Z. (b)Let W = X + Y and V = X + Y . Compute the joint distribution of W and V . after assiging the values to k matrix how can i find u

Of course, you'll probably have much better luck over there if you post what you've tried to solve this homework problem first, not just the homework question. -- Steve Lord slord@mathworks.com To contact Technical Support use the Contact Us link on http://www.mathworks.com

### What are tags?

A tag is like a keyword or category label associated with each thread. Tags make it easier for you to find threads of interest.

Anyone can tag a thread. Tags are public and visible to everyone.
