## Methods for Function logLik

### Description

Compute the log-likelihood.

### Methods

object = TopicModel:

  Compute the log-likelihood of a `"TopicModel"` object. For `"VEM"` objects 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.

object = Gibbs_list:

  Compute the log-likelihoods of the `"TopicModel"` objects contained in the `"Gibbs_list"` object.
