Exponential Distribution |
(continuous probability dist for equations) |
Usage: |
ExponentialDist (x, l) |
Definition: |
l exp (- l x) |
Required: |
l > 0 |
Support: |
x ³ 0 |
Moments: |
m = 1 / l s = 1 / l g1 = 2 b2 = 9 |
If events occur by a = 4 && typeof(BSPSPopupOnMouseOver) == 'function') BSPSPopupOnMouseOver(event);" class="BSSCPopup" onclick="BSSCPopup('X_PU_Poisson_process.htm');return false;">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).
