ConjointChecks (version 0.0.9)

ConjointChecs-package: ConjointChecks: A package to check the cancellation axioms of conjoint measurement.

Description

Implementation of a procedure (Domingue, 2012; see also Karabatsos, 2001 and Kyngdon, 2011) to test the single and double cancellation axioms of conjoint measure in data that is dichotomously coded and measured with error.
