dlso | R Documentation |
This function provides a partition to summarize a partition distribution
using the draws-based latent structure optimization (DLSO) method, which is
also known as the least-squares clustering method (Dahl 2006). The method
seeks to minimize an estimation criterion by picking the minimizer among the
partitions supplied. The implementation currently supports the minimization
of several partition estimation criteria. For details on these criteria, see
partition.loss
.

The loss function to use, as indicated by |
estimate |
An integer vector of cluster labels having the same length as
|
An integer vector giving the estimated partition, encoded using cluster labels.
