predictr - Predict the Reliability
predictr: predict + reliability, in other words: A tool to predict the reliability.
The aim of this package is to provide state of the art tools for all kinds of Weibull analyses.
predictr already includes many methods (see list below). A guideline on when to use which method will be added soon.
