SpletIn the above fX;Y and fY are pmf’s; in the continuous case they are pdf’s. With this notation we have E[XjY = y] = X x xfXjY (xjy) and the partition theorem is E[X] = X y E[XjY = y]P(Y = y) A.2 Conditional expectation as a Random Variable Conditional expectations such as E[XjY = 2] or E[XjY = 5] are numbers.

SpletOne-to-one I In Example 1, if we know Y = 2X, we uniquely know X and vice versa. In this case the transformation is one-to-one. I In Example 2, if we know Y AND we know that X is positive, we uniquely know X and vice versa. In this case the transformation is not generally one-to-one (because of SpletSuppose I have a random variable X ∼ Gamma ( k, θ), and I define Y = log ( X). I would like to find the probability density function of Y. I had originally thought I would just define cumulative distribution function X, do a change of variable, and take the "inside" of the integral as my density, like so, P ( X ≤ c) = ∫ 0 c 1 θ k 1 Γ ... SpletThe function f X Y ( x, y) is called the joint probability density function (PDF) of X and Y . In the above definition, the domain of f X Y ( x, y) is the entire R 2. We may define the range of ( X, Y) as. R X Y = { ( x, y) f X, Y ( x, y) > 0 }. The above double integral (Equation 5.15) exists for all sets A of practical interest. solio phone charger
