20.2 - Conditional Distributions for Continuous Random Variables

SpletA random variable is a map X: !R. We write P(X2A) = P(f!2: X(!) 2Ag) and we write X ˘P to mean that X has distribution P. The cumulative distribution function (cdf) of Xis F X(x) = F(x) = P(X x): A cdf has three properties: 1. F is right-continuous. At each x, F(x) = lim n!1F(y n) = F(x) for any sequence y n!xwith y n>x. 2. Fis non-decreasing ...
