Interpretation of Inconsistent Choice Data: How Many Context

My main result (Theorem 1) shows that if the number of orderings K is sufficiently small (relative to the number of possible orderings, |X|!), the probability p of erring in each choice is sufficiently low, and the choice implications of the preference orderings in R are sufficiently different (see ...

Flexible Fault Tolerant Subspace Clustering for Data with Missing
