The Mean Life Function
The mean life function, which provides a measure of the average time of operation to failure, is given by:


 * $$\mu = m =\int_{0,\gamma}^{\infty}t\cdot f(t)dt$$

It should be noted that this is the expected or average time-to-failure and is denoted as the MTBF (Mean-Time-Before Failure) and is also called MTTF (Mean-Time-To-Failure) by many authors.
