Weibull++ Life Data Folio

The Weibull++ life data folio for life data analysis is the most basic folio in the application. The objective of life data analysis is to fit a statistical distribution to failure time data in order to understand the reliability performance of a product over time or to make projections about future behavior. From the analysis, you can estimate metrics such as probability of failure, reliability, mean life or failure rate. The ReliaWiki resource portal has more information on the basics of life data analysis at http://www.reliawiki.org/index.php/Life_Data_Analysis_Reference_Book.
