The probability density function f(x) of a continuous random variable is the analogue of the probability mass function p(x) of a discrete random variable. Here are two important differences: 1. Unlike p(x), the pdf f(x) is not a probability. You have to integrate it to get proba­ bility. (See section 4.2 below.) 2.
