WebThe Cumulative Distribution Function (CDF), of a real-valued random variable X, evaluated at x, is the probability function that X will take a value less than or equal to x. It is used to describe the probability distribution of random variables in a table. And with the help of these data, we can easily create a CDF plot in an excel sheet. Web2 The cumulative distribution function (CDF) The cumulative distribution function (CDF) of a random variable X is: The following properties of the CDF of X: • and; is a non-decreasing function on R. • If X is a discrete random variable then: If X is a continuous random variable then: is a continuous function on R.
