Implements a variety of functions to approximate expected ranks for partial rankings.
approx_rank_expected(P, method = "lpom")
A partial ranking as matrix object calculated with neighborhood_inclusion or positional_dominance.
String indicating which method to be used. see Details.
The method parameter can be set to
local partial order model
extension of the local partial order model.
based on a connection with relative rank probabilities.
extension of the previous method.
Which of the above methods performs best depends on the structure and size of the partial
