5 Reliability Data Analysis and Model Selection
In Chapter 3, we discussed several common distribution models useful for reliability analysis of items. It is necessary at this point to discuss how field and reliability test data can support the selection and estimation of the parameters of a probability distribution model for reliability analysis. In this chapter, we first describe the types of data used in reliability model development, then we discuss the common procedures for selecting and estimating the model parameters using data and information. These procedures can be divided into two groups: nonparametric methods (that do not need a particular distribution function) and parametric methods (that are based ...
