The Weibull distribution is one of the most widely used lifetime distributions in reliability engineering. It can model an increasing, decreasing and or constant failure rate behavior.  The 3-parameter Weibull includes a location parameter gamma. It's pdf is given by:
|-
| align="center" valign="middle" |
<br><math> f(T)={ \frac{\beta }{\eta }}\left( {\frac{T-\gamma}{\eta }}\right) ^{\beta -1}e^{-\left( { \frac{T-gamma}{\eta }}\right) ^{\beta }} \,\!</math>
<br>Beta is the shape parameter or slope. Values less than one incicate a decreasing failure rate, greater then one an increasing failure rate, and when one a constant failure rate. Eta is the scale parameter, or characteristic life.  Eta represents the time by which 63.2% of the units fail.<br>
<br><math> \beta= </math> shape parameter (or slope).
