Nonparametric tests of the necessary and sufficient conditions for separability
We survey the current state of the art in the use of nonparametric methods to test separability. We focus on three tests: Swofford and Whitney's (1994) joint test of the necessary and sufficient conditions for weak separability; Fleissig and Whitney's (2003) sequential test of those conditions; and Jones and Stracca's (2006) test of the necessary and sufficient conditions for additive separability
