Example 11.4: MLEs for Two-Parameter Weibull Distribution

This example considers a data set given in Lawless (1982). The data are the number of days it took rats painted with a carcinogen to develop carcinoma. The last two observations are censored. Maximum ...

Weibull Plots Predict System Reliability

• Weibull plots fit a curve through data, not data to a predetermined distribution’s curve. • After evaluating subsystems, their Weibull data is combined to represent the complete system. Weibull ...
