Description
Assigns each ranking the probability that it belongs to
each cluster, given current parameters.
Usage
1
Arguments
R
Current cluster modal sequences.
r
The data of partial or full rankings.
p
The proportion of the data currently assigned to
each cluster.
lambda
The lambda parameters from Mallow's model
for each cluster.
G
Number of clusters, length(R).
N
Number of rows in the data.
C
Vector of normalizing coefficients for the
clusters.
all.dists
For efficiency, provide all of the
Kendall distances between each sequence and each cluster
mode.
Value
Matrix where output[i, j] represents the current
probability that subject "i" belongs to cluster "j".
