WebMarginal probability density function. by Marco Taboga, PhD. Consider a continuous random vector, whose entries are continuous random variables.. Each entry of the random vector has a univariate distribution described by a probability density function (pdf). This is called marginal probability density function, to distinguish it from the joint probability density … WebThe marginal PDF of X can be found as follows: By symmetry, the marginal PDF of Y must take on the same functional form. Hence, the product of the marginal PDFs is Clearly, this is not equal to the joint PDF, and therefore, the two random variables are dependent. This conclusion could have been determined in a simpler manner.
