✦ Synopsis

A BS TRA C T Two generalized classes of the concept 'new better than used', namely the new better than used in failure rate and the new better than used in average failure rate classes of life distributions are considered. The relations between these three classes are established through the partial ordering of the tail heaviness. Two test statistics for the generalized classes based on the empirical distributions are derived and their exact distributions are investigated. The distributions of these statistics are tabulated for some small samples. The power of the tests is studied for some common distributions in reliability modelling.

Partial orderings are used to compare ageing behaviour of components or systems. In this paper a new partial ordering, namely the renewal superadditivity, is introduced. This concept is used to characterise the new better than renewal used criterion of ageing. The dual criterion the new worse than r

## Abstract Family‐based association tests (FBATs) provide simple and powerful tests to detect association between a genetic marker and a disease‐susceptibility locus, manifest in subjects by a phenotype or disease trait. Here we propose a new class of conditional tests for family‐based association
