Likelihood {RMallow}

Likelihood of the data and parameters.

Description

Calculates the log-likelihood of the data with the current parameters and Kendall's distance.

Usage

Arguments

z

Probability of each cluster membership.

p

Proportion in each cluster.

C.lam

Vector of normalizing coefficients for Mallows' model.

lambda

Current spread parameters

all.dists.data
