We present a new synthesizer for categorical data based on the Quasi-Multinomial distribution. Characteristics of the Quasi-Multinomial distribution provide a tuning parameter, which allows a Quasi-Multinomial synthesizer to control the balance of the utility and the disclosure risks of synthetic data. We develop a Quasi-Multinomial synthesizer based on a popular categorical data synthesizer, the Dirichlet process mixtures of products of multinomial distributions. The general sampling methods and algorithm of the Quasi-Multinomial synthesizer are developed and presented. We illustrate its balance of the utility and the disclosure risks by synthesizing a sample from the American Community Survey.
