The Exponential Distribution
The exponential distribution is commonly used for components or systems exhibiting a constant failure rate and is defined in its most general case by:
 * $$f(t)=\lambda {e}^{-\lambda(t-\gamma )}$$

(also known as the two-parameter exponential in this form) with two parameters, namely $$\lambda $$ and  $$\gamma .$$ If the location parameter, $$\gamma $$, is assumed to be zero, the distribution then becomes the one-parameter exponential or,
 * $$f(t)=\lambda {{e}^{-\lambda t}}$$

The exponential distribution and its characteristics are presented in more detail in Chapter The Exponential Distribution.
