A continuous random variable is said to be hyperexponential (or mixed exponential) when its probability density function is the convex sum of exponential density functions. Often, the term hyperexponential is used only when the mixture has two terms, written in such a way that there are just two parameters instead of the usual 2n − 1 for a mixed exponential with n terms.
