related models is given in Section 7. Finally, Section 8 concludes the paper. 2. Latent Dirichlet Allocation and Hierarchical Dirichlet Process Model We start by reviewing the LDA and HDP models. Both LDA and HDP are generative probabilistic models for discrete data such as bags of words from text documents Œ in this context these models The Dirichlet process (DP) is a distribution over distributions (Ferguson, 1973). It is denoted, G˘DP( G 0); (2) where Gis a random distribution. There are two parameters. The base distribution G 0is a distribution over the same space as G. For example, if Gis a distribution on reals then G 0must be a distribution on reals too. The proposed interactive latent Dirichlet allocation (iLDA) model develops deterministic and stochastic approaches to obtain subjective topic-word distribution from human experts, combines the subjective and objective topic-word distributions by a linear weighted-sum method, and provides the inference process to draw topics and words from a comprehensive topic-word distribution. The proposed Continuous Multivariate Distributions, Volume 1, Second Edition provides a remarkably comprehensive, self-contained resource for this critical statistical area. It covers all significant advances that have occurred in the field over the past quarter century in the theory, methodology, inferential procedures, computational and simulational aspects, and applications of continuous multivariate Continuous Multivariate Distributions, Volume 1, Second Edition provides a remarkably comprehensive, self-contained resource for this critical statistical area.

The power of this connection is illustrated via a posterior inference algorithm to estimate phase-type distributions, avoiding some difficulties with the simulation of latent We show that one can compute the probability integral of Dirichlet distribution by the use of our program which computes the probability integral of inverted Dirichlet distribution.
