WebbSection 5: Distributions of Functions of Random Variables. As the name of this section suggests, we will now spend some time learning how to find the probability distribution of functions of random variables. For example, we might know the probability density function of X, but want to know instead the probability density function of u ( X) = X 2. WebbA cumulative distribution function (CDF) describes the probabilities of a random variable having values less than or equal to x. It is a cumulative function because it sums the total likelihood up to that point. Its output always ranges between 0 and 1. CDFs have the following definition: CDF (x) = P (X ≤ x)

A cumulative distribution function (cdf) tells us the probability that a random variable takes on a value less than or equal to x. For example, suppose we roll a dice one time. If we let x denote the number that the dice lands on, then the cumulative distribution function for the outcome can be described as ... log in to my immi account
