Lambda: Objective function to determine lambda.

In RMallow: Fit Multi-Modal Mallows' Models to Ranking Data

Description

Objective function to find the root of in calculating the lambda parameters for each cluster.

Usage

  Lambda(lambda, rhs, dists, dists.table = NULL)

Arguments

lambda	lambda value to calculate the function output at.
rhs	Right-hand side of the equation in the referenced paper.
dists	Not used.
dists.table	Table of distances between each sequence and the modal sequence in N! space.

Value

Output of the objective function to determine the root of. Goal is zero.
