Let v be a random variable distributed according to F(.). Let X be a set containing the objects x1 and x2. Suppose
E(v|x1) = b AND E(v|x2) = b (The expected value of v conditional on x1 is b, etc)
where b is some constant.
Does it follow that E(v|x1,x2) = b? If so, why?
Additionally, does the converse hold?
i.e. does E(v|x1,x2) = b imply E(v|x1) = b and E(v|x2) = b?
Thank you!
