Let be a continuous random vector having joint probability density functionThe marginal probability density function of is obtained by integrating the joint probability density function with respect to . When , thenWhen , thenTherefore, the marginal probability density function of is See more A more formal definition follows. Recall that the probability density function is a function such that, for any interval , we havewhere is the probability that will take a value in the interval . … See more The marginal probability density function of is obtained from the joint probability density function as follows:In other words, the marginal probability density function of is obtained by integrating the joint probability density … See more Marginal probability density functions are discussed in more detail in the lecture entitled Random vectors.

All the examples in this section and the previous one have started with a joint density function that apparently emerged out of nowhere. In the next section, we will study a context in which they arise WebMarginal density function. Marginal density function can be defined as the one that gives the marginal probability of a continuous variable. Marginal probability refers to the probability of a particular event taking place without knowing the probability of the other variables. It basically gives the probability of a single variable occurring. cinemark manhattan ks
