Description
Updates the Lambda parameters to maximize the likelihood
of the data under Mallows' model.
Usage
1
2
UpdateLambda(r, R, z, G, dists.to.Rg, dists.table,
top.bound = 1000)
Arguments
r
Matrix of partial rankings.
R
Current modal sequences.
z
Current probabilities of memberships in each
cluster.
G
Number of modal sequences.
dists.to.Rg
Matrix of the distances between the
data and the current modal sequences.
dists.table
Table of the distance distribution in
N! space, under Kendall's metric.
top.bound
The maximum value for the lambda
parameter.
Value
Vector of new lambda parameters for the clusters.
