意味（1）

(statistics) Any of a class of continuous probability distributions used to model the time between events that occur independently at a constant average rate.

The exponential distribution is a basic distribution for constructing a number of other distributions. For example, the gamma distribution is obtained from the distribution of the sum of random variables where each variable follows an exponential distribution.
