Read this article to learn about the marginal rate of substitution! The marginal rate of substitution is the rate of exchange between some units of goods X and Y which are equally preferred. ms excel tutorial pdf free download An abbreviated version of the problem statement in the book is: Given a joint pdf for X and Y : fX,Y (x,y) =? 2 3(x + 2y), 0 ≤ x ≤ 1,0 ≤ y ≤ 1 0, o.w. (a) Find the marginal pdf of X. (b) Find the marginal pdf of Y . (c) Find P [X < 0.5]. Additionally, (d) Find the covariance of X and Y . (e) Find the correlation coeﬃcient, ρXY .

## And The Marginal Pdf Of Y

Consider the joint pdf of $(X, Y)$ given by $$f(x, y) = \begin{cases} e^{-y} & \text{ if } 0 < x < y < \infty \\ 0, & \text{ otherwise} \end{cases} $$

- and Y have continuous distributions, it becomes more important to have a systematic way to That is, the joint density f is the product of the marginal †marginal densities densities g and h. The word marginal is used here to distinguish the joint density for.X;Y/from the individual densities g and h. ⁄ When pairs of random variables are not independent it takes more work to ﬁnd a
- Let X and Y have the joint probability density function f X, Y ( x, y ) = x + 4y for 0 < y < x < 1, 0 otherwise. a) Find the marginal p.d.f.s f X (x) and f Y (y).
