In TopKLists: Inference, Aggregation and Visualization for Top-K Ranked Lists

Description

Spearman's footrule is a measure for distance between ranked lists. It is given as the sum of absolute differences between ranks of two lists. Here a modified version is implemented that allows for comparing partial lists.

Usage

Spearman(rank.a, rank.b, k.a, k.b, n)

Arguments

rank.a	A single top-k list
rank.b	A vector of matrix form of top-k list(s) to be compared to the list a
k.a	Value of k for rank.a
k.b	Value of k for rank.b
n	Total number of objects, numbered from 1 to n

Value

Returns modified Spearman distance against a for each lists within b
