Weibull Analysis

Weibull Analysis is a methodology for determining reliability characteristics and trends from field and/or test data. It allows decisions to be made based on a limited amount data. A special case with very few data points is WeiBayes Analysis. Results for a two-parameter Weibull Analysis provide estimates of an improving/degrading reliability trend (value of β) and the characteristic life (value of η, the estimated time at which 63.2% of a population will have failed due to a specific failure mode).
