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 several life characteristics, such as probability of failure, reliability, mean life or failure rate.
Bayesian analysis methods are based on the concept that the probability of an event or behavior can be predicted from previous pieces of evidence related to the occurrence of that event or behavior. The Bayesian-Weibull method combines prior information about the failure behavior of a product, along with current observations, in order to make predictions about the life characteristics of the product. This type of analysis is particularly useful when there is limited life data for a given product or failure mode but there is a strong prior understanding of the failure rate behavior.

Standard Folio Bayesian-Weibull Distribution with Lognormal Prior

Bayesian analysis methods are based on the concept that the probability of an event or behavior can be predicted from previous pieces of evidence related to the occurrence of that event or behavior. The Bayesian-Weibull method combines prior information about the failure behavior of a product, along with current observations, in order to make predictions about the life characteristics of the product. This type of analysis is particularly useful when there is limited life data for a given product or failure mode but there is a strong prior understanding of the failure rate behavior.
