Weibull++ Standard Folio Data 1P-Weibull

 

The One-Parameter Weibull Distribution The one-parameter Weibull distribution is a special case of the two parameter Weibull that assumes that shape parameter is known constant, [math]\displaystyle{ \beta=C=Constant \,\! }[/math] or [math]\displaystyle{ R(t)=e^{-\left( {\frac{t}{ \eta }}\right) ^{C}} \,\! }[/math] In this formulation we assume that the shape parameter is known a priori from past experience on identical or similar products. The advantage of doing this is that data sets with few or no failures can be analyzed.
