Reason for reverting alleged property

edit

The following uncited alleged property was put in on 4 December 2011 by a single-edit anon:

"If X, Y are two different random variables such that X is mean independent of Y and Z = f(X), which means that Z is a function only of X, then Y and Z are mean independent."

I'm reverting this because the following is a counterexample: Let Y take on either of two values   and   and say that if   then   while if   then   and say   Then   regardless of y, yet if   then   so   while if   then   so   Loraof (talk) 22:19, 2 August 2017 (UTC)Reply
