WebFeb 28, 2024 · The marginal distribution The picture guides us: it suffices to consider only − 2 ≤ y ≤ 2. It often is simpler to compute a cumulative distribution function F Y (and differentiate it if you really need the density f Y ), so we might start with that. Here, its value at y would be the total probability below the horizontal line at height y.

Marginal Density Function For joint probability density function for two random variables X and Y , an individual probability density function may be extracted if we are not concerned with the remaining variable. In other words, the marginal density function of x from f ( x, y) may be attained via: Example: asian gsm mallWebMarginal Distribution and Marginal Den-sity: (X,Y ) has the joint pdf f(x,y).
