Statistical Analysis of Reliability Field Data When Working Conditions are Imprecisely Reported

In contrast to laboratory lifetime tests reliability field tests are usually performed in conditions which vary in time in a random way. We consider the case when users are asked about their description of their vague perceptions of the usage conditions. In the paper we use interval-valued variables for the description of imprecisely known test conditions that may be used as covariates in classical reliability models. We present a simple approximate algorithm for a proportional hazard lifetime model.
