Exponential Distribution |
(continuous probability dist for equations) |
Usage: |
ExponentialDist (x, λ) |
Definition: |
λ exp (- λ x) |
Required: |
λ > 0 |
Support: |
x ⋝ 0 |
Moments: |
μ = 1 / λ σ = 1 / λ γ1 = 2 β2 = 9 |
If events occur by a Poisson process, then the time between successive events is described by the exponential distribution (where l is the average number of events per unit time).
