Integral of conditional probability
NettetWikipedia - conditional expectation: Then a conditional expectation of X given H, denoted as E ( X ∣ H), is any H -measurable function ( Ω → R n) which satisfies: ∫ H E ( X ∣ H) d P = ∫ H X d P for each H ∈ H. Firstly, it is a H -measurable function. Secondly it has to match the expectation over every measurable (sub)set in H. http://sims.princeton.edu/yftp/emet13/PDFcdfCondProg.pdf

Nettet24. apr. 2024 · By the Radon-Nikodym theorem, named for Johann Radon and Otto Nikodym, X has a probability density function f with respect to μ. That is, P(A) = P(X ∈ A) = ∫Afdμ, A ∈ S In this case, we can write the expected value of g(X) as an integral with respect to the probability density function. If g: S → R is measurable then, assuming … NettetI We can de ne the conditional probability density of X given that Y = y by f XjY=y(x) = f(x;y) f Y (y).

I We can de ne the conditional probability density of X given that Y = y by f XjY=y(x) = f(x;y) f Y (y) I This amounts to restricting f (x;y) to the line corresponding to the given y value (and dividing by the constant that makes the integral along that line equal to 1).
