Find marginal pdf from joint pdf
WebFeb 19, 2010 · To find the marginal PDF of X, integrate the joint PDF with respect to Y, and set your bounds of integration as the range of Y. Similarly, to find the marginal PDF … WebViewed 14k times. 6. We can get the joint pdf by differentiating the joint cdf, Pr ( X ≤ x, Y ≤ y) with respect to x and y. However, sometimes it's easier to find Pr ( X ≥ x, Y ≥ y). Notice that taking the complement doesn't give the joint CDF, so we can't just differentiate and flip signs. Is there still some simple rule to ...
