    sufficient statistic for joint geometric distribution




    I wonder if someone could check the attached document regarding my attempt at a Fisher-Neyman factorization of a joint geometric pdf.

    Thanks

    X+Y-2 or X+Y is the sufficient statistic here.


    Here h(x) =1 T(x) = X+Y and
    g(z) = θ^2(1- θ)^( z– 2)
    In the long run, we're all dead.
