    Independence versus conditional indenpendce




    Independence versus conditional independence. Consider x and y independent Gaussian
    random variables with zero mean and unity variance.
    1. For an arbitrary new random variable does the following hold
    P(X, Y|z) = P(x|z) * P(ylz) ?
    2. Let z = x + y . Write the explicit expression of the pdf p( x, y | z) . Use the Dirac delta
    function if necessary.


    pls help

    double post, but...

    1. no

    2. look up Poisson-Multinomial relationship for example; in general, no
    The mathematical explanation of a statistical procedure is really just pseudo-code, which we can make operational by translating it into real computer code. --B. Klemens
