New $U$-empirical tests of symmetry based on extremal order statistics, and their efficiencies

open access: yes, 2014
We use a characterization of symmetry in terms of extremal order statistics which enables to build several new nonparametric tests of symmetry. We discuss their limiting distributions and calculate their local exact Bahadur efficiency under location ...
