WebMar 2, 2024 · Exponential Distribution: PDF & CDF. If a random variable X follows an exponential distribution, then the probability density function of X can be written as: f(x; λ) = λe-λx. where: λ: the rate parameter (calculated as λ = 1/μ) e: A constant roughly equal to 2.718. The cumulative distribution function of X can be written as: F(x; λ) = 1 ... WebIn probability theory and statistics, the Laplace distribution is a continuous probability distribution named after Pierre-Simon Laplace.It is also sometimes called the double exponential distribution, because it can be thought of as two exponential distributions (with an additional location parameter) spliced together along the abscissa, although the term …
