comment How to show that measurable functions preserve mean independence?
I never said conditional density = conditional expectations. I said $E(X∣Y=y) =\int_{-\infty}^\infty x f_{X|Y}(x|y) dx$

comment How to show that measurable functions preserve mean independence?
tell me what makes no sense and I'll be happy to clarify. Conditional expectations are defined as in Ross's "A First Course in Probability" ins.sjtu.edu.cn/people/lqyan/Teaching/TeachingPDF/…

I define it as $\int_{-\infty}^\infty x f_{X|Y}(x|y) dx$. Maybe I should have added that joint and conditional distributions of $X$ and $Y$ exist etc.
