01 Overview of Distribution Fitting & Reliability

Module 3 Assessing & Selecting Models for Time-to-Failure Data

Lesson M03-01

Text: Section 5  pages 1 – 4

Duration: 12 minutes

In this lesson, we introduce the approach for selecting models that adequately describe the time to failure data.  Models selected in this step will be subsequently used to estimate reliability metrics of interest.  A graphical tool (Probability Plot) for assessing model fit is introduced.  While some details of constructing probability plots are introduced, the emphasis will be on applying this tool to determine models that adequately describe the data.
