The Scroogefactor is PageRank divided by out-degree. It can be used as an approximate estimator for the Bradley–Terry model.

a damping factor |
sort |
logical. Reorder the indices in descending order of Scroogefactor score |
Pinksi and Narin (1976) first proposed this metric as a citation metric called the influence per reference. When applied to citation data, it can be interpreted as the influence per outgoing reference, effectively penalising larger publications and review journals, which have larger combined bibliographies. When applied to sports or games results, it is influence per game lost.
A vector equivalent to PageRank per reference, scaled to sum to one
