The Exponential Distribution
The exponential distribution is commonly used for components or systems exhibiting a constant failure rate. It is defined in its most general case by:


 * f(t) = λe− λ(t − γ)

with two parameters, namely λ and γ (this form is also known as the two-parameter exponential). If the location parameter, γ, is assumed to be zero, then the distribution becomes the one-parameter exponential or,


 * f(t) = λe− λt

The exponential distribution and its characteristics are presented in detail in the Exponential Distribution chapter.
