cluster_est_binder: Point estimate of the partition for the Binder loss function

Description

Get a point estimate of the partition using the Binder loss function.

Usage

cluster_est_binder(c, logposterior)

Arguments

c

a list of vector of length n. c[[j]][i] is the cluster allocation of observation i=1...n at iteration j=1...N.

logposterior

vector of logposterior correponding to each partition from c used to break ties when minimizing the cost function

Value

a list:

• c_est: a vector of length n. Point estimate of the partition
• cost: a vector of length N. cost[j] is the cost associated to partition c[[j]]
• similarity: matrix of size n x n. Similarity matrix (see similarityMat)
• opt_ind: the index of the optimal partition among the MCMC iterations.
