Methods for Function logLik

Description

Compute the log likelihood.

Methods

object = VEM:
Compute the log likelihood of a VEM topic model object. The sum of the log likelihood of all documents given the parameters for the topic distribution and for the word distribution of each topic is approximated using the variational parameters and underestimates the log likelihood by the Kullback-Leibler divergence between the variational posterior probability and the true posterior probability.
