| === The Three-Parameter Weibull Distribution ===
| |
| | |
| The three-parameter Weibull ''pdf'' is given by:
| |
| | |
| <math> f(t)={ \frac{\beta }{\eta }}\left( {\frac{t-\gamma }{\eta }}\right) ^{\beta -1}e^{-\left( {\frac{t-\gamma }{\eta }}\right) ^{\beta }} </math>
| |
| | |
| where,
| |
| | |
| <math> f(t)\geq 0,\text{ }t\geq 0\text{ or }\gamma, </math>
| |
| | |
| <math>\beta>0\ \,\!</math>,
| |
| | |
| <math> \eta > 0 \,\!</math>,
| |
| | |
| <math> -\infty < \gamma < +\infty \,\!</math>
| |
| | |
| and,
| |
| | |
| <math> \eta= \,\!</math> scale parameter, or characteristic life <math> \beta= \,\!</math> shape parameter (or slope),
| |
| | |
| <math> \gamma= \,\!</math> location parameter (or failure free life).
