Various phylogenetic problems (such as DNA, protein and genome reconstruction) involve estimating the ancestral states at the root of a tree from data at the tips (leaves). A better understanding of various methods of ancestral reconstruction would help us determine their reliability and credibility. This project investigates the upper and lower bound for the correct probability of reconstructi...

We develop a general concept of majority rule for finitely many choice alternatives that is consistent with arbitrary binary preference relations, real-valued utility functions, probability distributions over binary preference relations, and random utility representations. The underlying framework is applicable to virtually any type of choice, rating, or ranking data, not just the linear orders...
