The Three-Parameter Weibull Distribution
The three-parameter Weibull pdf is given by:

$$ f(t)={ \frac{\beta }{\eta }}\left( {\frac{t-\gamma }{\eta }}\right) ^{\beta -1}e^{-\left( {\frac{t-\gamma }{\eta }}\right) ^{\beta }} $$

where,

$$ f(t)\geq 0,\text{ }t\geq 0\text{ or }\gamma, $$

$$\beta>0\ \,\!$$,

$$ \eta > 0 \,\!$$,

$$ -\infty < \gamma < +\infty \,\!$$

and,

$$ \eta= \,\!$$ scale parameter, or characteristic life $$ \beta= \,\!$$ shape parameter (or slope),

$$ \gamma= \,\!$$ location parameter (or failure free life).
