This example appears in the Accelerated Life Testing Data Analysis Reference book.
Consider the following times-to-failure data at two different stress levels.
The data set was analyzed jointly in an ALTA standard folio using the IPL-Weibull model, with a complete MLE solution over the entire data set. The analysis yields:
- [math]\displaystyle{ \widehat{\beta }=2.616464\,\! }[/math]
- [math]\displaystyle{ \widehat{K}=0.001022\,\! }[/math]
- [math]\displaystyle{ \widehat{n}=1.327292\,\! }[/math]
