subsection{Conditional expectation}
subsubsection*{Definitions}
Let $(Omega,mathcal{F},P)$ be a probability space.
begin{definition}[conditional expectation]label{def:conditional_expectation}
Let $mathcal{G}$ be a sub-$sigma$-algebra (sub-$sigma$-field) of $mathcal{F}$. We define
the emph{conditional expectation} $E(X|mathcal{G})$ (or $E(X|mathcal{G})$, when there
is no risk of confusion) as any $mathcal{G}$-measurable random variable such that
[ E[1_A E(X|mathcal{G})] = E[1_A X] ]
for every $A in mathcal{G}$. In particular $E(X|mathcal{G})$ is uniquely determined
on sets $A$ with $P(A)>0$. We also say that $E(X|mathcal{G})$ is emph{$L^1$-version} if
[ E[|E(X|mathcal{G})|] = E[|X|] ]
and it exists iff $X in L^1(Omega,mathcal{F},P)$.
We say that $E(X|mathcal{G})$ is emph{$L^r$-version} if
[ E[|E(X|mathcal{G})|^r] = E[|X|^r] ]
and it exists iff $X in L^r(Omega,mathcal{F},P)$.
If $X$ is $mathcal{G}$-measurable then $E(X|mathcal{G}) = X$.
If ${mathcal G_n}_{n=1}^infty$ is an increasing sequence
of sub-$sigma$-algebras (i.e., $mathcal G_n subseteq mathcal G_{n+1}$) then
[ E(E(X|mathcal G_n)|mathcal G_{n+1}) = E(X|mathcal G_{n+1}). ]
This property is called tower property or law of iterated expectations.
In particular,
[ E(E(X_1 + X_2 |sigma(X_1))|sigma(X_1,X_2)) = E(X_1 + X_2 |sigma(X_1,X_2)) = X_1 + E(X_2 |sigma(X_1,X_2)). ]
If ${mathcal G_n}_{n=1}^infty$ is a decreasing sequence
of sub-$sigma$-algebras (i.e., $mathcal G_n supseteq mathcal G_{n+1}$) then
[ E(E(X|mathcal G_n)|mathcal G_{n+1}) = E(X|mathcal G_{n+1}). ]
The following limit theorem holds:
Let ${mathcal G_n}_{n=1}^infty$ be an increasing sequence
of sub-$sigma$-algebras such that $bigcup_{n=1}^infty mathcal G_n =: tilde{mathcal G}$
is also a sub-$sigma$-algebra. Then if $X in L^1(Omega,tilde{mathcal G},P)$ then
[ Y := lim_{n to infty} E(X|mathcal G_n) = E(X|tilde{mathcal G}) ]
where convergence is almost surely.
We say that $X$ is $tilde{mathcal G}$-emph{$L^r$-integrable} if $X in L^r(Omega,tilde{mathcal G},P)$.
We say that ${mu_n : n=0,1,dots,infty}$ is a regular conditional probability distribution if
$mu_n(A) = P(A|sigma(Y_n))$
for some random variables ${(Y_n : n=0,1,dots,infty)}$ such that
$sigma(Y_n) =: tilde{mathcal G}_n$
and $bigcup_{n=0}^infty tilde{mathcal G}_n =: tilde{tilde{mathcal G}}$
is also a sub-$sigma$-algebra.
We have
[ P(A | Y) := P(A | sigma(Y)) := P(A | Y^{-1}(Omega)). ]
This means that for every Borel set $B$, we have
[ P(A | Y)(w) := P(A | Y^{-1}(B))(w). ]
In general we have
[ P(A | Y)(w) := P(A | Y^{-1}(Y(w))) := P(A | Y^{-1}(Y(w)))(w). ]
This means that if $Y(w) = b$, then we have
[ P(A | Y)(w) := P(A | Y^{-1}(b))(w). ]
For example if we have two random variables $Y,Z$, then we have
[ P(A | Y,Z)(w) := P(A | Y^{-1}(Y(w)),Z^{-1}(Z(w))) := P(A | Y^{-1}(Y(w)),Z^{-1}(Z(w)))(w). ]
In particular,
[ P(Y=y,Z=z|Y=y,Z=z) := 1. ]
Note that conditional probability may not be measurable; for example,
if we take $A=emptyset$, then clearly we have
[ P(emptyset | Y,Z)(w) := 0. ]
However this function need not be measurable.
For example if we have random variables $(X,Y)$ defined as follows:
[ X(w):= w;~~~ Y(w):=left( w - [w] - 0.5 + 0.25(-)^{lfloor w + 0.5rfloor}right)/0.25;~~~ w >0;~~~ (X,Y):=(0,(0))~~~ w=0;~~~ (X,Y):=(+infty,(+infty))~~~ w<0;~\(X,Y)sim U([0;+infty)times[0;+infty)). ]
Then we can show that
[ E(Y|X=x)=x-lfloor x+0.5rfloor-0.5~~~ x >0;~~~ E(Y|X=x)=(x-lfloor x+0.5rfloor-0.5)^+~~~ x<0;~~~\E(Y|X=x)=E(Y)=(x-lfloor x+0.5rfloor-0.5)^++(x-lfloor x+0.5rfloor-0.5)^-=0~~~ x=0;~~~\P(Y=y|X=x)=P((Y=y)cap (X=x))=P((Y=y)cap (x-lfloor x+0.5rfloor-0.5+(-)^{lfloor x+0.5rfloor}/4=y))=P((x-lfloor x+0.5rfloor-0.5+(-)^{lfloor x+0.5rfloor}/4=y),\P(x-lfloor x+0.5rfloor-0.5+(-)^{lfloor x+0.5rfloor}/4=y)=P(x=lfloor x+0.5rfloor+y+frac12-frac14(-)^{lfloor x+0.5rfloor}). \]
It follows that
[ P(Y=y|X=x)=P(x=lfloor x+0.5rfloor+y+frac12-frac14(-)^{lfloor x+0.5rfloor})=delta(y-left(x-lfloor x+0.5rfloor-0.5+frac14(-)^{lfloor x+0.5rfloor}right)). \]
Note that this function is not measurable because it has jump discontinuity at points where $x=n+frac12$, where $n$ is an integer.
To see this note first that
[ P((x-lfloor x+0.5rfloor-0.5+(-)^{lfloor x+0.5rfloor}/4=y),\P(x-lfloor x+0.5rfloor-0.5+(-)^{lfloor x+0.5rfloor}/4=y)=P(x=lfloor x+0.5rfloor+y+frac12-frac14(-)^{lfloor x+0.5rfloor}). \]
Moreover note that
[ (forall y)(y=left(x-lfloor x+0.5rfloor-0.bar{}.bar{}.bar{}.bar{}.bar{}.bar{}.bar{}.bar{}.bar{}.bar{}.bar{}.bar{}.bar{}.bar{}.bar{}.bar{}.bar{}.bar{}.bar{}right)+q),~~q<+infty; ~~y=left(left(x-frac12+frac14(-)^{lflooooorx+.50}right)-[left(x-.50+.04(-)^{flooorx+.50}right)]+.50-.04(-)^{flooor[left(x-.50+.04(-)^{flooorx+.50}right)]}right)+q),\q<+infty \implies ynot=left(x-frac12+.04(-)^{flooorx+.50}right); ~~ynot=left(left(x-.50+.04(-)^{flooorx+.50}right)-[left(x-.50+.04(-)^{flooorx+.50}right)]+.50-.04(-)^{flooor[left(x-.50+.04(-)^{flooorx+.50}right)]}right);\ynot=x-frac12+.04(-)^{{flooortype(y)}};]
here ${flooortype(y)}:= {flooortype(left(y-frac12+.04(-)^{{flooortype(y)}}+frac12-.04(-)^{{flooortype(y)}})}$
since
[ ynot=left(x-frac12+.04(-)^{{flooortype(y)}}+frac12-.04(-)^{{flooortype(y)}})right)=ynot=x;]
moreover
[ (forall y)(y=xnot=left(x-frac12+.04(-)^{{flooortype(y)}})not=left(left(x-.50+.04(-)^{{flooortype(y)}})right)-[left(x-.50+.04(-)^{{flooortype(y)}})right)]+.50-.04(-)^{{flooortype(y)}});]
so
[ (forall y)(ynot=left(x-frac12+.04(-)^{{flooortype(y)}})not=left(left(x-.50+.04(-)^{{flooortype(y)}})right)-[left(x-.50+.04(-)^{{flooortype(y)}})right)]+.50-.04(-)^{{flooortype(y)}});]
so
[ (forall y)((y=left(x-frac12+.04(-)^{{flooortype(y)}})iff y=x);\(y=left(left(x-.50+.04(-)^{{flooortype(y)}})right)-[left(x-.50+.04(-)^{{flooortype(y)}})right)]+.50-.04(-)^{{flooortype(y)}})iff y=x);\(ynot=left(x-frac12+.04(-)^{{flooortype(y)}})iff ynot=x);\(ynot=left(left(x-.50+.04(-)^{{
