Exponential distribution

Exponential distribution and Gamma distribution
We establish here that the sum of n iid Exp(Î") distributed random variables is distributed as Gamma(n, 1/Î").
Random sum of exponential random variables ...

Exponential Distribution. If T is the time between occurrences of rare events that happen on the average with a rate l per unit of time, then T is distributed exponentially with parameter l (lambda).

The alternative story is more plausible in terms of foreperiod distributions; previous work showing a larger foreperiod effect among 5-7 year olds used an exponential distribution of intervals, ...
