KendallMLists {TopKLists}

KendallMLists

Description

Compute Kendall's tau criterion

Usage

KendallMLists(input, space = NULL, aggregate, p = 0.5, w = NULL)

Arguments

input

A list with each element being a top-k list to be aggregated; the top-k lists can be of variable lengths

space

A list with each element being the underlying space from which the corresponding top-k list is derived

aggregate

The aggregate list (result) from any of the three classes of algorithms

p

A parameter between 0 and 1 for setting the distance of a pair of elements between two lists, if at least one of the elements is not in the underlying space of one of the list or if both elements belong to one list but neither belongs to the other list. (We recommend using p=0.5 for a "neutral approach".)

w

Weight vector assigning a weight to each list

Value

Kendall's distance
