Multivariate distribution : Mean vector?

  1. Nov 21, 2009 #1
    Hello friends.My English is bad :) .I'll try to explain my trouble.

    In question: Q function according to x1 and x2 are substitutes when the joint comes out of solution. Of the solution in theory I do not understand where they come from.Is there another solution or the problem? Where is the theoretical? Can you please explain mathematically?


    Probabilty density function:


    Multivariate normal distibitions

    mean vector of the universe?
