Properties

The exponential distribution curve is defined as follows:

ExponEq

The areas above a give value may be determined by the following equation:

ExponAreaEq

The mode of the distribution is the minimum value.

The standard deviation of the exponential distribution is equal to the distance from the mean to the minimum value.
