WebNov 5, 2024 · What is the correct formula for the marginal PDF of X? I think I have to start off by integrating c 1 + x 2 + y 2 with respect to y. Which gives me ∫ c 1 + x 2 + y 2 d y = c ∗ arctan y 1 + x 2 1 + x 2 But don't know how to continue now. I'd also like to know if there's any software out there where I can compute this kind of symbolic stuff.

WebVisually, the shape of this conditional density is the vertical cross section at \(x\) of the joint density graph above. The numerator determines the shape, and the denominator is part of the constant that makes the density integrate to 1. Note that \(x\) is constant in this formula; it is the given value of \(X\). http://prob140.org/textbook/content/Chapter_17/03_Marginal_and_Conditional_Densities.html
WebSuppose the joint density of X and Y is given by f (x, y) = k (y 2 − x 2) e − y, 0 < y < ∞, − y ≤ x (a) Find k. (b) Determine the marginal density function f Y (y). (c) Compute Cov [X, Y]. (d) Show that E [X ∣ Y = y] = 0. If X is uniform over (0, 1), calculate E [X n] and Var (X n).
