Modeling the Reliability of Ball Bearings

Modeling the Reliability of Ball Bearings

The data, created by Chrys Caroni of the National Technical University of Athens, presented in this article refer to the reliability of ball bearings in manufacturing. The data was originally published by "Lieblein and Zelen" and contains 210 observations. Rather than exploring the data to obtain a multiple linear regression solution, a theoretically derived equation is given and the data is used to test it. Some of the key concepts includes: failure times, percentiles and weighted least squares.
