2P-Weibull MLE Solution for Multiple Right Censored Data |
This example validates the calculations for a 2-parameter Weibull MLE solution with likelihood ratio bound for right censored data in Weibull++ standard folios.
Reference Case
The data set in Table C.5 on page 633 of the book Statistical Methods for Reliability Data by Dr. Meeker and Dr. Escobar, John Wiley & Sons, 1998 is used.
