WebLet X and Y be random variables (discrete or continuous!) with means μ X and μ Y. The covariance of X and Y, denoted Cov ( X, Y) or σ X Y, is defined as: C o v ( X, Y) = σ X Y = E [ ( X − μ X) ( Y − μ Y)] That is, if X and Y are discrete random variables with joint support S, then the covariance of X and Y is: C o v ( X, Y) = ∑ ∑ ... WebThe joint cumulative distribution function of two random variables X and Y is defined as FXY(x, y) = P(X ≤ x, Y ≤ y). As usual, comma means "and," so we can write FXY(x, y) = P(X ≤ x, Y ≤ y) = P ((X ≤ x) and (Y ≤ y)) = P ((X ≤ x) ∩ (Y ≤ y)). Figure 5.2 shows the region associated with FXY(x, y) in the two-dimensional plane.
