Consistent Subsets – Computationally Feasible Methods to Compute the Houtman-Maks-Index
Heufer, Jan; Hjertstrand, Per - 2014
We provide two methods to compute the largest subset of a set of observations that is consistent with the Generalised Axiom of Revealed Preference. The algorithm provided by Houtman and Maks (1985) is not comput ationally feasible for larger data sets, while our methods are not limited in that...
