Linear MMSE

  1. May 30, 2013 #1
    I am not able to understand how to go about this problem:

    Find the minimum mean square estimator for the scalar parameter w based
    on the scalar observation z = ln w + n where
    f(w) =1 if 0<=w<=1;
    0 else:

    f(n) =e^-n if n>= 0;
    0 else

    I did f(z/w) = (f(n)) /g'(n) at n = z- ln w

    Am i wrong?

    Hey sant142 and welcome to the forums.

    Can you show us what estimator you got (as a function of a random sample I.I.D) and the calculations you obtained for the MSE (and proof that it is MMSE)?
