weibulltools

Unlike other R packages for survival analysis, the weibulltools package focuses on reliability methods and has the advantage of being open source and easily accessible contrary to other reliability analysis software. In addition to that the package can be integrated into (partly) automated data analytics processes and even connected to big data systems.

The weibulltools package contains methods for examining bench test or field data using the well-known weibull analysis. It includes Monte Carlo simulation for estimating the life span of products that have not failed, taking account of registering and reporting delays. On this basis, if the products looked upon are vehicles, the covered mileage can be estimated as well. The weibulltools package also provides methods for probability estimation within samples that contain failures as well as censored data.Methods for estimating the parameters of lifetime distributions as well as the confidence intervals of quantiles and probabilities are also included and, if necessary, data can automatically be divided into subgroups using segmented regression. Besides the calculation methods, methods for interactive visualization of the edited data using Plotly are provided as well.
