ABSTRACT
The idea of intersection-union (IU) tests appeared in Gleser (1973) and has been made popular by Berger (1982). Casella and Berger (1990, Chapter 8) provided a very readable introduction. These tests have been found to be very useful in bio-equivalence studies; see e.g., Hsu et al. (1994), Berger and Hsu (1996) and Wellek (2003).
