Life Data Analysis for Reliability Engineers - Weibull Analysis, Detailed Plots, Compute Statistics
Project description
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.
Main Features
Parameter Estimation
- Uncensored two-parameter Weibull distribution
- Type I and type II right-censored two-parameter Weibull distribution
- Bx-life calculator

Bias-correction methods
- C4 method (reduced bias adjustment)
- Hirose and Ross method
- Non-Parametric Bootstrap correction (mean, median, trimmed mean)
- Parametric Bootstrap correction (mean, median, trimmed mean)
Confidence bounds
