Ranking

During my PhD, I studied how to analyze preference data in the form of total orders/permutations or pairwise comparisons, and how to handle statistical problems related to such data, including ranking aggregation, distribution estimation, and prediction. Here is the final version of the manuscript and the slides; and below a list of publications.
