Pitfalls and Practical Considerations in Product Life Analysis—Part II: Mixtures of Product Populations and More General Models

Abstract

This is the second part of a two-part paper. The first part dealt with some basic concepts and pitfalls of the analysis of product life data and presented two examples that illustrated the problems of extrapolation. In this part, we discuss problems in dealing with life data from a mixture of product populations, propose some general models for product life and suggest some remedial approaches.
