 2d accepted When combining p values, why not just averaging? Dec5 comment When combining p values, why not just averaging? Thank you for your answer. The intuition you mentioned actually makes sense. I would consider those cases you mentioned as more significant. But is there a way to express this idea more mathematically rigorously?

Justification and reason for the procedure Sep30 accepted Proof for E[X|X] = X Sep29 comment Proof for E[X|X] = X @Anh Is it that when $X=t$, t comes out of the integral, and that the integral integrates to one, therefore it's t? Sep29 comment Proof for E[X|X] = X Thank you for your answer. But I have no idea what $\sigma(Y)$ and $A\in\sigma(Y):EX1_A=EZ1_A$ mean. Where can I learn more about them? Sep29 comment Proof for E[X|X] = X Thank you for your answer. Can I ask why the join pdf is equal to $f_x(X)\delta(x-X)$? and where can I learn more about it? Sep29 comment Proof for E[X|X] = X What do you mean by integrating over the range for which $X=x$? is it integrating from negative infinity upto x? That still would not give me the correct answer. I am confused as I am not doing anything illegal upto $\int{xdx}$. I just don't know how to go from here to x due to my limiting knowledge.
